Recent Advances in Black Hole Research and Stability

Recent research advances in black hole studies have focused on their stability and new theoretical frameworks. A paper on Buchdahl limits in theories with regular black holes discusses how certain configurations can be more compact than those predicted by Einstein gravity, suggesting the existence of stars with finite central pressures that exceed traditional limits.

Another study investigates the mass and entropy of eternal quantum black holes in two dimensions, revealing thermal stability under specific conditions, while yet another explores nonsingular hairy black holes formed via gravitational decoupling, producing solutions that bridge classical and novel geometries.

Additionally, research on black hole solutions in Horava gravity shows that linear equations of state can lead to exotic behaviors, while a study on spin-induced quadrupole moments highlights how eccentric binaries can be misidentified as non-black hole binaries, emphasizing the importance of accurately accounting for orbital eccentricity in future gravitational wave observations.
