CompOSE - http://compose.obspm.fr CompStar Online Supernovae Equations of State

main purpose: interface for developers and users of EoS

Realization: http://compose.obspm.fr• online repository of tabulated EoS (supports HDF5 and plain format)

- data format specifically developed to account for thermodynamic and microphysical quantities, as well as matter composition- format focuses on ability to extend format to not yet specified quantities→ easy to provide every calculated quantity

• data sheet for every provided EoS- describes available quantities, described particles, and basic relevant propertiesas saturation properties or maximum neutron star mass if available

• interpolation routines- enables EoS user to extract data in own favored format- provide derivative terms not given by developer

• comprehensive manual and personal support- 75 pages manual (http://compose.obspm.fr and arXiv:1307.5715)- contact develop.compose@obspm.fr (S. Typel, M. Oertel, T. Klähn)

main purpose: interface for developers and users of EoS

- about 50 registered users- A number of representative EoS in full n-T-Ye – plane:

- Lattimer/Swesty 220 w/ or w/o Λ (Oertel et al.)- TM1, TMA, NL3, DD2, FSG,IUF w/ nuclei (Hempel et al.)- More to come

- 2 key issues:1. need to provide as many EoS as possible: currently about 20

2. make EoS users realize the advantages of CompOSE:- one unique data format for all available EoS, one time effort to get used to it (compare to: each developer provides as he provides, unless you’re friends)- precise and tested interpolation routines, thermodynamic consistent- EoS are well documented (abstract, data index, key properties, references)

1. and 2. are connected: PLEASE advertise! PLEASE provide! PLEASE use!
