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…
Are nonrelativistic ground state -boson stars only stable for and ?
Emmanuel Chávez Nambo, Armando A. Roque, Olivier Sarbach
In previous work we analyzed the linear stability of non-relativistic -boson stars with respect to radial modes and showed that ground state configurations are stable with re…
