Abstract

The problem of resonance in a geocentric Satellite under the combined gravitational forces of theSun and the Earth due to Poynting-Robertson (P-R) drag has been discussed in this paper with theassumption that all three bodies, the Earth, the Sun and the Satellite, lie in an ecliptic plane. Ourapproach differs from conventional ones as we have placed evaluated velocity of the Satellite inequations of motion. We observed five resonance points commensurable between the mean motionof the Satellite and the average angular velocity of the Earth around the Sun, out of which tworesonances occur only due to velocity dependent terms of P-R drag. Amplitudes and time periodsare periodic with respect to the angle (angle between direction of vernal equinox and the directionof the Sun) which have been evaluated graphically in this paper. We have also found that amplitudeas well as time-period decreases as orbital angle of the Earth around the Sun increases in the firstquadrant.

1. Introduction

The problem of resonance in the Solar system is one of the important problem and it plays asignificant role in dynamical system. Resonance happens when any two or more frequencies arecommensurable. Out of five general types of resonances, the most obvious type in a planetarysystem is mean motion resonance, which occurs when orbital periods of two Satellites or planetsare close to a ratio of small integers.

Poynting (1903); Robertson (1937) investigated that the radiation pressure, the Doppler shift ofthe incident radiation and the Poynting drag are the three terms which generally constitutes theradiation force on a particle exerted by a radiating body. Frick and Garber (1962) have studied thein-plane perturbations of a geosynchronous Satellite under the gravitational forces of the Moon,the Sun and the oblate Earth. They have assumed that all the three bodies (Sun, Moon, Earth)lie in the plane of ecliptic and have also assumed that orbital plane of the Satellite and referenceplane coincide with the Earth’s equatorial plane. Brouwer (1963) has discussed the resonancein the motion of an artificial satellite caused by Solar radiation pressure. Bhatnagar and Gupta(1977) examined resonance in the motion of an artificial Earth’s Satellite caused by Solar-Radiationpressure. They expanded Hamiltonian and the generating function in the power series of a smallparameter, which depends on Solar Radiation pressure. Bhatnagar and Mehra (1986) have alsodiscussed the motion of geosynchronous Satellite under the combined gravitational effects of Sun,Moon and the oblate Earth with radiation pressure of the Moon. They have shown that orbitalplane of the synchronous Satellite rotates with an angular velocity lying between 0.0420 per yearand 0.0580 per year. They also observed that regression period increases as both orbital inclinationand the altitude increase. The radial deviation and the tangential deviation have been determined inthe in-plane motion of a geosynchronous Satellite under the gravitational effects of the Sun, Moonand the oblate Earth by Bhatnagar (1990).

Ragos (1995) numerically studied the existence and stability of equilibrium points for particlesmoving in the vicinity of two massive bodies which exert light radiation pressure. Ragos and Vra-hatis (1995) have discussed the photo-gravitational circular restricted three body problem includingthe P-R effect to describe the effect in the vicinity of two massive radiating bodies. A modified bi-section method is used to compute the position of the equilibrium and thereby establishing thestability. Liou and Zook (1995) have explored the effect of radiation pressure, P-R drag, and Solarwind drag on the dust grains trapped in the mean motion resonances with the Sun and Jupiter inthe restricted three body problem (R3BP) with negligible dust mass. They especially examined theevolution of dust grain in the 1:1 resonances. Kushvah (2009) investigated the effect of P-R drag onlinear stability of equilibrium points in the generalized photo gravitational Chermnykh’s problemwhen a bigger primary is radiating and a smaller primary is an oblate spheroid. It was found thatwhen P-R effect is taken into account, these points were unstable in a linear sense.

Some results on the dynamics of the regularised R3BP with dissipation have been discussed byAlessandra Celletti et al. (2011). They found that a large fraction of test particles with initial con-ditions in the interior region collides with the Sun. They also found out many interesting and impor-tant results. By taking two bodies, one luminous and another non-luminous in elliptical three-bodyproblem Jagdish et al. (2012) studied the motion of infinitesimal mass around seven equilibrium

points. There exists conditional stability around triangular points. Lhotka et al. (2014) surveyedthe stability of motion to the Lagrangian equilibrium points L4 and L5 in the framework of thespatial elliptic restricted three body problem, subject to the radial component of P-R drag. Yadavand Aggarwal (2013a, 2013b, 2014, 2015), in the series of papers, discussed the resonances ina geo-centric synchronous Satellite under the gravitational forces of the Moon, the Sun and theEarth including its equatorial ellipticity. The amplitude and the time period of the oscillation wasdetermined by using the procedure of Brown and Shook (1933).

Jain and Aggarwal (2015) investigated the existence of non-collinear liberation points and theirstability in the circular restricted three body problem in which they considered the smaller primaryas an oblate spheroid and bigger one a point mass including the effect of dissipative forces, es-pecially Stokes drag. Other studies regarding resonance or P-R drag may be seen in Mehra et al.(2016), Lhotka et al. (2016) and Pushparaj and Sharma (2017).

In majority, authors have discussed only two of the three i.e. P-R drag, three-body problem orresonance. We have taken into account all of the three above, which makes our work different fromothers. This paper aims to find the resonance in the motion of geocentric Satellite under Poynting-Robertson drag of the three-body problem. Diligent scrutinization of equations of motion in Sect.2 of this paper unveils that there are five points Ri’s, i = 1 − 5, of resonance in the motion of theorbiting satellite due to the presence of m and β where m is the mean motion of the satellite andβ the average angular velocity of the sun. Amplitudes and time periods at resonance points havebeen evaluated in Sect. 3. This section also explores the variation of amplitude and time periodwith respect to β and different values of q. The paper ends with the Sect. 4 where the discussionsand conclusions are presented.

2. Statement of the problem and Equations of motion

Let S represent the Sun, E the Earth and R the Satellite with their masses MS , ME and MR respec-tively. The Satellite moves around the Earth in an ecliptic plane with angular velocity ~ω∗ and thesystem is also revolving with the same angular velocity ~ω∗. Let ~r

E, ~rs and ~r represent the vectors

from Sun and Earth, Sun and Satellite and Earth and Satellite respectively; γ be the vernal equinoxand c0 the velocity of light. Let X, Y , Z be the co-ordinate system of the Satellite with origin at thecenter of the Earth with unit vectors I, J and K along the co-ordinates axes respectively. Let X0,Y0 and Z0 be another set of co-ordinate system in the same plane, with origin at the center of theEarth, and unit vectors I0 ,J0 and K0 along the co-ordinate axes respectively (Figure 1(b)). Let ~FRbe the Poynting-Robertson drag per unit mass acting on the Satellite due to radiating body (Sun)in the arbitrary direction as shown in Figure 1(a), given by

MR~FR = ~f1 + ~f2 + ~f3, (Ragos, 1995)

Equations (3) and (4) are the required equations of motion of the Satellite in polar form. Theseequations are not integrable, therefore we follow the perturbation technique and replace r and α,

where

r2α = constant,l = a(1− e2),e, ω = constants of integration,

Let us consider

α− ω = f = α0t = mt(say).

Since e < 1, we have

(1 + e cosmt)h1 ≈ 1 + h1e cosmt.

On simplifying Equation (7) we get

where Pi’s are are given in the Appendix A. It is clear that the motion becomes indeterminate if anyone of the denominator vanishes in equation (9), which are the points at which resonance occurs.It is found that resonance occurs at five points m = β, m = 2β, 3m = β, 2m = β, 3m = 2β. The2:1 resonance repeated twice, 1:1 resonance occurs thrice while other resonances occur only once.Out of all resonances, the 3:2 and 1:2 resonances occurs only due to P-R drag. We have also foundout the amplitude and time period at these resonance points.

3. Time period and amplitude atm = β

In our problem, the solution of Equation (8) is periodic and known which is a condition of Brownand Shook (1933). So we follow the same to determine time periods and amplitudes at n = β. It is

u = v cos p,

where

p = mt+ ε,

m =v1v

= function of v; (11)

v, v1 and ε are arbitrary constants. As we are probing the resonance in the motion of the Satelliteat the point m = β, the resulting Equation (9) can be written as

Since the last expression of Equation (19) has the factor L2 it may, in general, be neglected in afirst approximation. In Equation (12) we find p and t are present in ψ as sum of the periodic termswith argument

In the same manner we have calculated amplitudes and time periods at other points. Thereafter twocases arise:

Case 1 If we take only Solar radiation pressure as perturbing force, then there are only three pointsR1(m = β), R2(3m = β), R3(2m = β) at which resonance occurs. At critical point m = β we getamplitude A3 and time-period T3. Corresponding amplitudes and time-periods of our findings aregiven in table 2 below.

Case 2 In addition to the above, if we consider velocity dependent terms of P-R drag, then fivepoints R1(m = β), R2(3m = β), R3(2m = β), R4(3m = 2β), R5(m = 2β) of resonance occur wherethree points of resonance are same as in case 1, and 1 : 2 and 3 : 2 resonances occur only due to

In the present study the resonance in the motion of the Satellite in the Sun-Earth-Satellite systemhave been studied under the influence of P-R drag effect by using the method of Brown and Shook(1933). Firstly, we have derived the equations of motion of the geocentric Satellite in vector formand further this equation is converted to polar form to obtain two system of equations, so that wecan apply the well known method discussed by Brown and Shook. Next, it is found that thereare five points R1(m = β), R2(3m = β), R3(2m = β), R4(3m = 2β), R5(m = 2β) at whichresonances occur where m ≈ α0 is average angular velocity of a Satellite and β is average angularvelocity of the Earth. The 2:1 resonance occurs twice, 1:1 resonance occurs thrice while 1:2, 3:1and 3:2 resonances occur only once. There are two resonance points 3:2 and 1:2 occur only due

to velocity dependent terms of P-R drag. If we ignore perturbing force then resonance will occuronly at three points in the equation of motion of a Satellite. We have shown the effect of P-R dragon amplitudes and time-periods. Further, we have evaluated the amplitudes and time periods ofthe Satellite numerically by using, data mentioned in Appendix A. From Figure 2, we observethat amplitude and time-period increases when q increases and it is maximum at β = 0. p is thefactor of velocity dependent terms of P-R drag, when q increases p decreases and hence whenP-R decreases then amplitude as well as time-period increases. Figure 3 explains the variation inA1 and time-period T1 respectively for −900 < β < 900 and 0 < q < 1, at resonance 1 : 1 withP-R drag. Above graphs show that amplitude and time-period decreases as β increases. Figure 4also explains the amplitude and time period with respect to β. In this case it can be observed thatamplitude becomes very high of greater range of β but it is not in the case of velocity dependentterms of P-R drag. Similarly, Figure 5 explains the variation in amplitude for −900 < β < 900

and 0 < q < 1 at resonance 1 : 2. Graphs show that amplitude is periodic with respect to β and itincreases (decreases) when q increases (decreases).
