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…
Spinning gravimagnetic particles in Schwarzschild-like black holes
Walberto Guzmán-Ramírez, Ricardo Becerril, Susana Valdez-Alvarado +1
We study the motion of a spinning particle with gravimagnetic moment in Schwarzschild-like spacetimes with a metric , specifically we d…
Mass parameter and the bounds on redshifts and blueshifts of photons emitted from geodesic particle orbiting in the vicinity of regular black holes
Ricardo Becerril, Susana Valdez -Alvarado, Ulises Nucamendi +2
We obtain the mass parameter for a class of static and spherically symmetric regular black holes (BHs) (namely Bardeen, Hayward and Ayón-Beato-García BHs) which are solutions of Ei…
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…
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…
Obtaining mass parameters of compact objects from red-blue shifts emitted by geodesic particles around them
Ricardo Becerril, Susana Valdez-Alvarado, Ulises Nucamendi
The mass parameters of compact objects such as Boson Stars, Schwarzschild, Reissner Nordstrom and Kerr black holes are computed in terms of the measurable redshift-blueshift (zred,…
