Heavy ion collisions in the 1A GeV regime: how well do we join up to astrophysics?

Abstract

The derivation of information useful for understanding the physics inside compact stars from HIC observations is a difficult task. Complications due to finite size, different chemistry, non-adiabatic compression, incomplete stopping and structural effects must be overcome. This can only be convincingly achieved by a successful simulation of many experimental observables varying incident energy, system size and isospin content. Using now available systematic FOPI data in the SIS energy range we try to trace the path to take.
