Masses of compact (neutron) stars with distinguished cores
Masses of compact (neutron) stars with distinguished cores
Zöllner, R.; Ding, M.; Kämpfer, B.
The impact of the core mass on the compact/neutron-star mass-radius relation is studied.
Besides the mass, the core is parameterized by its radius and surface pressure, which supports the outside one-component Standard Model (SM) matter.
The core may accommodate SM matter with unspecified (or poorly known) equation-of-state or several components, e.g.\ consisting of admixtures of Dark Matter and/or Mirror World matter etc.\ beyond the SM. Thus, the admissible range of masses and radii of compact stars can be considerably extended.
Keywords: compact stars; core-corona decomposition; impact of core mass; Dark-Matter admixture
