CompOSE - CompStar Online Supernovae Equations of State

Abstract

This paper is the manual of the CompOSE service, see http://compose.obspm.fr, an equation of state (EoS) database for use in nuclear physics and in astrophysical applications, e.g. the simulation of core-collapse supernovae and compact stars. The main aims of the service are the following: to offer a robust, easily extendable data format to store and read EoS data tables and related physical quantities; to make these data available to the public -- respecting the original work by the contributors -- in a standard format designed for easy access and flexibility; and to provide routines to interpolate these data in the parameter space of density, temperature and hadronic charge fraction. The manual contains a detailed description of the service. It is divided into three parts, containing a general introduction as well as instructions for potential contributors and for users.
