We obtain the mass parameter for a class of static and spherically symmetric regular black holes (BHs) (namely Bardeen, Hayward and Ay\'{o}n-Beato-Garc\'{i}a BHs) which are solutions of Einstein's field equations coupled to nonlinear electrodynamics

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 stability analysis of fermion-boson stars that include a quartic self-

A deformed embedding of the Reissner-Nordstr{\o}m spacetime is constructed within the framework of a noncommutative Riemannian geometry. We find noncommutative corrections to the usual Riemannian expressions for the metric and curvature tensors, whic

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, zblue) of photons emitted by particles moving along circular geodesic

Compact objects, like neutron stars and white dwarfs, may accrete dark matter, and then be sensitive probes of its presence. These compact stars with a dark matter component can be modeled by a perfect fluid minimally coupled to a complex scalar fiel

The boson-fermion stars can be modeled with a complex scalar field coupled minimally to a perfect fluid (i.e., without viscosity and non-dissipative). We present a study of these solutions and their dynamical evolution by solving numerically the Eins

We search for equilibrium configurations of the (coupled) Einstein‐Klein‐Gordon equations for the case of a real scalar field endowed with a quartic self‐interaction potential. The resulting solutions are the generalizations of the (massive) os

We solve numerically the Einstein–Klein–Gordon (EKG) system, assuming spherical symmetry, for a real scalar field endowed with a quartic self-interaction potential, and obtain the so-called oscillatons: oscillating soliton stars. We obtain the eq

We investigate the stability of oscillatons with a quartic self-interaction. Oscillatons are spherically symmetric solutions of the coupled Einstein-Klein-Gordon for the case of a real scalar field. It is shown that there exist equilibrium configurat
