Relativistic and Newtonian Proca Stars: A Tale of Two Limits
Alberto Diez-Tejedor, Carlos Herdeiro, Claudio Lazarte +4
We investigate a representative set of static solitonic solutions of the Einstein-Proca theory in the Newtonian regime, where the field frequency approaches the particle mass, $Ï\…

Phase Structure of Scalarized Black Holes in Einstein-Scalar-Gauss-Bonnet Gravity
Carlos Herdeiro, Hyat Huang, Jutta Kunz +3
We revisit scalarized black holes in Einstein-scalar-Gauss-Bonnet gravity and analyze the thermodynamic phase transition between the Schwarzschild solution of general relativity an…

Phase transitions of boson stars in scalar-tensor theories
Hyat Huang, Burkhard Kleihaus, Jutta Kunz +3
In scalar-tensor theories, compact objects may experience spontaneous scalarization. Recently, it was shown that matter-induced spontaneous scalarization of neutron stars is predom…
