P36 v2. 0: Phase Diagram of Compact Objects in CCEGA — Updated Boundaries: Mₘax

Key Points

To update the phase boundaries for compact objects in the context of CCEGA and M_max.
Updated phase boundaries following previous classification P34 v2.0.
Retained the same methods used in earlier versions.
Identified three regimes: NS with masses less than 4.56 solar masses, ultracompact from 4.56 to 12.0, and CCEGA black holes above 12.0.
GW190814 reclassified as a candidate for a massive neutron star.

Abstract

Updates phase boundaries following P34 v2. 0 (Mₘax = 4. 56 ± 0. 03 M☉). Three regimes: NS (M 12. 0). GW190814 reclassified as massive NS candidate. Method unchanged from v1. 1.
