Existence of nonrelativistic - and multi--boson stars and their radial stability
Emmanuel Chávez Nambo, Olivier Sarbach
Using direct methods of the calculus of variations we establish the existence of an infinite class of spherically-symmetric solutions to the multi-field Schrödinger-Poisson system…

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…

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…
