Buchdahl limits in theories with regular black holes
Pablo Bueno, Robie A. Hennigar, Ángel J. Murcia +1
We study generalizations of Buchdahl's compactness limits for perfect-fluid star solutions of -dimensional Einstein gravity coupled to higher-curvature corrections. We focus on…
Husain-Kuchař model as the Carrollian limit of the Holst term
J. Fernando Barbero G., Juan Margalef-Bentabol, Aitor Vicente-Cano +1
We show how the Husain-Kuchař model can be understood as a Carrollian limit of the Holst term in the context of background-independent field theories described in terms of coframes…
Regular black holes from Oppenheimer-Snyder collapse
Pablo Bueno, Pablo A. Cano, Robie A. Hennigar +2
It has been recently shown that regular black holes arise as the unique spherically symmetric solutions of broad families of generalizations of Einstein gravity involving infinite…
