Radial Oscillations of Quark Stars in Strong Magnetic Fields

Abstract

The eigenfrequencies of radial pulsations of quark stars are calculated in a general relativistic formalism given by Chandrasekhar in the density-dependent quark mass model in strong magnetic fields. It is found that the squares of the frequencies are always decreasing functions of the central density of the strange star. The maximum mass, the radius, and gravitational redshift of the star are increasing functions of the magnetic field.
