CompOSE reference manual

Abstract

CompOSE (CompStar Online Supernovae Equations of State) is an online repository of equations of state (EoS) for use in nuclear physics and astrophysics, e.g., in the description of compact stars or the simulation of core-collapse supernovae and neutron-star mergers, see . The main services, offered via the website, are: a collection of data tables in a flexible and easily extendable data format for different EoS types and related physical quantities with extensive documentation and referencing; software for download to extract and to interpolate these data and to calculate additional quantities; webtools to generate EoS tables that are customized to the needs of the users and to illustrate dependencies of various EoS quantities in graphical form. This manual is an update of previous versions that are available on the CompOSE website, at , and that was originally published in the journal “Physics of Particles and Nuclei” with . It contains a detailed description of the service, containing a general introduction as well as instructions for potential contributors and for users. Short versions of the manual for EoS users and providers will also be available as separate publications. Graphical Abstract

Equations of state for dense matter and astrophysical constraints

“…Data tables, associated software, and the manual, can be freely downloaded, cf. Dexheimer et al (2022); Typel et al (2022).…”

Pulsar timing anomalies: a window into baryon number violation

“…To calculate the b-factors crucial to our analysis, we generated a sequence of static, non-rotating neutron stars using the DS(CMF) EoS [47]-the first hadronic variant that includes a crust [48], as documented in the CompOSE database [49]. Detailed descriptions of the EoS, including its Lagrangians and particle constituents, are provided in ref.…”

The QCD Phase Diagram at High Densities: An Experimental Overview

“…We note the existence of the online service CompOSE repository that provides data tables for different state of the art EoSs ready for use in astrophysical applications, nuclear physics and beyond[136][137][138].…”
