Proto-neutron stars with heavy baryons and universal relations.

RADUTA A.R., OERTEL M. and SEDRAKIAN A.

Abstract (from CDS):

We use covariant density functional theory to obtain the equation of state (EoS) of matter in compact stars at non-zero temperature, including the full baryon octet as well as the Δ(1232) resonance states. Global properties of hot Δ-admixed hypernuclear stars are computed for fixed values of entropy per baryon (S/A) and lepton fraction (YL). Universal relations between the moment of inertia, quadrupole moment, tidal deformability, and compactness of compact stars are established for fixed values of S/A and YL that are analogous to those known for cold catalyzed compact stars. We also verify that the I-Love-Q relations hold at finite temperature for constant values of S/A and YL.
