TL;DR: In this paper, a generalized relativistic harmonic oscillator for spin 1∕2 particles is studied, and analytical solutions for bound states of the corresponding Dirac equations are found.

TL;DR: In this paper, the effect of electric charge in compact stars was studied and the authors concluded that the electric fields have to be huge to have any appreciable effect on the phenomenology of the compact stars, which implies that the total charge is Coulomb.

TL;DR: In this paper, the authors derived the hydrostatic equilibrium configuration of neutron stars and strange stars, whose fluid pressure is computed from the equations of state for the f(R,T) theory of gravity, with $R$ and $T$ standing for the Ricci scalar and trace of the energy-momentum tensor, respectively.

TL;DR: In this paper, the authors study the hydrostatic equilibrium configuration of neutron stars and strange stars, whose fluid pressure is computed from the equations of state p=ωρ5/3 and p=028(ρ−4ℬ), respectively, with ω and ℬ being constants and ρ the energy density of the fluid.

TL;DR: The possible existence of compact stars made of absolutely stable strange quark matter was pointed out by Witten almost a quarter of a century ago as discussed by the authors, and one of the most amazing features of such objects concerns the possible existence a ultrastrong electric fields on their surfaces, which, for ordinary strange matter, is around 10.5 V/cm.
