The continuum spectrum of nonrelativistic multi-frequency Proca stars
Galo Diaz-Andrade, Alberto Diez-Tejedor, Jose Luis Medina-Garcia +1
Multi-frequency Proca stars are excited selfgravitating solutions of the Schrödinger-Poisson system that generalize the conventional stationary states of a massive vector fi…
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\…
Linear stability of nonrelativistic Proca stars
Emmanuel Chávez Nambo, Galo Diaz-Andrade, Alberto Diez-Tejedor +3
We study the linear stability of nonrelativistic Proca stars under generic perturbations. Using a combination of analytic and numerical methods, we demonstrate that, as expected, t…
Compact stars in Einstein-scalar-Gauss-Bonnet gravity: regular and divergent scalar field configurations
Roberto D. Alba Q., Javier Chagoya, Armando A. Roque
We investigate static, spherically symmetric solutions in Einstein-scalar-Gauss-Bonnet gravity non-minimally coupled to a massless real scalar field, both in vacuum and in the pres…
Signatures of cubic gravity in the strong regime
Flavio C. Sánchez, Armando A. Roque, Javier Chagoya
We investigate the effects of Einsteinian cubic gravity in the strong gravitational regime. In the first part, we explore analytical solutions for a static, spherically symmetric m…
Nonrelativistic Proca stars: Spherical stationary and multi-frequency states
Emmanuel Chávez Nambo, Alberto Diez-Tejedor, Edgar Preciado-Govea +2
In this paper we follow an effective theory approach to study the nonrelativistic limit of a selfgravitating and selfinteracting massive vector field. Our effective theory is chara…
