Observations of compact stars and fermion-boson stars with a quartic self-interaction
Susana Valdez-Alvarado, Alejandro Cruz-Osorio, J. M. Dávila +2
We investigated the possibility that compact stars could be described by a fermion-boson star with a quartic self-interaction in the boson sector. Specifically, by varying the poly…
Fermion-boson stars with a quartic self-interaction in the boson sector
Susana Valdez-Alvarado, Ricardo Becerril, L. Arturo Ureña-López
Fermion-boson stars are solutions of the gravitationally coupled Einstein-Klein-Gordon-Hydrodynamic equations system. By means of methods developed in previous works, we perform a…
Bounds on spinning particles in their innermost stable circular orbits around rotating braneworld black hole
Ulises Nucamendi, Ricardo Becerril, Pankaj Sheoran
We study the innermost stable circular orbit (ISCO) of a spinning test particle moving in the vicinity of an axially symmetric rotating braneworld black hole (BH). We start with th…
Static dilaton space-time parameters from frequency shifts of photons emitted by geodesic particles
Susana Valdez-Alvarado, Ricardo Becerril, Francisco Astorga
The mass parameter of dilaton space-times is obtained as a function of the redshift-blueshift (zred, zblue) of photons emitted by particles orbiting in circular motion around these…
Oscillatons
Susana Valdez-Alvarado, Ricardo Becerril, L. Arturo Urena-Lopez
We solve numerically the Einstein-Klein-Gordon system with spherical symmetry, for a massive real scalar field endowed with a quartic self-interaction potential, and obtain the so-…
Numerical studies of Phi^2-Oscillatons
Miguel Alcubierre, Ricardo Becerril, F. Siddhartha Guzman +3
We present an exhaustive analysis of the numerical evolution of the Einstein-Klein-Gordon equations for the case of a real scalar field endowed with a quadratic self-interaction po…
