P36 v2.1: Phase Diagram of Compact Objects in CCEGA — Three Regimes from Neutron Stars to Black Holes

Key Points

• This research aims to update the phase diagram of compact objects within the CCEGA framework.
• Analyzed mass regimes of compact objects: neutron stars, ultracompact horizonless objects, and black holes.
• Conducted GR consistency check across different density limits.
• Quantified radion contributions to compact object formation.
• Identified three mass regimes: M < 4.56 M_sun for neutron stars, 4.56–12.0 M_sun for horizonless objects, and M > 12.0 M_sun for black holes.
• Confirmed GR consistency with Oppenheimer–Volkoff limit at low density.
• Detailed radion contributions demonstrate support for neutron stars and formation of black stars.
