Additional Programme definition

Asteroseismology with data from exoplanetary

Exoplanetary research with data from

asteroseismology fields

Any other science, not related to

asteroseismology or exoplanetary research.

perhaps few windows (max. of 64 available) with 32 sec integration time

perhaps 4 to 5 runs, about 20 days each. exo- and/or seismo-fields - if application is accepted.

Archival Data

access within proprietary time:

Identification of windows before launch necessary

after public release of archive:

no restrictions

In general:

Core program requirements will have priority

Data Policy

Open to Guest Investigators:

(a) about half of short runs will be available to specific target fields not devoted to seismology in the seismology field or planet search in the exo planet field.

(b) parallel science goals using data obtained under the Core programme or under the Additional Program (a).

For the Additional Program, individuals or groups will bid against an AO and if successful become Guest-Investigators (GIs) and will have exclusive data rights for the science of their program - the CoRoT Science Committee having rights for other uses of the same data.

The selection for additional programs will be made by the CoRoT Science Committee who will take into account the quality of science and the level of contribution by participating countries and ESA.

Public release of data: 1 year after the first release of data to the Co-Is or GIs.planet field

(January 2005)

deadline for proposals: e/o March 2005

selection of proposals:

during SC14 (after CSW8 in May 2005)

Important Questions

Which scientific programme do you intend to submit for the first year of CoRoT operation within the Additional Programme?

Have you identified your targets in the Seismo- or Exofield?

If not yet, how do you intend to obtain this information ?

If yes, include them as soon as possible in the AP_EXO data base

by sending your list to W.W.
