We report on the study of the mass-radius (M–R) relation and the radial oscillations of magnetized proto strange stars. For the quark matter we have employed the very recent modification, the temperature- and density-dependent quark mass model of t

We report on the study of the mass-radius (M-R) relation and the radial oscillations of proto strange stars. For the quark matter we have employed the well known density dependent quark mass model and its very recent modification, the temperature and

We study the effect of inclusion of muons and the muon neutrinos on the phase transition from nuclear to quark matter in a magnetised proto-neutron star and compare our results with those obtained by us without the muons. We find that the inclusion o

The eigen frequencies of radial pulsations of neutron stars are calculated in a strong magnetic field. At low densities we use the magnetic BPS equation of state(EOS) similar to that obtained by Lai and Shapiro while at high densities the EOS obtaine

In this paper we study quasi-radial oscillations of slowly rotating strange stars in strong magnetic fields in the density-dependent quark mass (DDQM) model. We see that the difference in frequency of rotating and non-rotating stars is more for highe

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 ar

We have studied the bulk viscosity of strange quark matter in the density dependent quark mass model (DDQM) and compared results with calculations done earlier in the MIT bag model where u, d masses were neglected and first order interactions were ta

The effect of strong magnetic field on the bulk properties of quark matter is reinvestigated takingu, d ands-quarks as well as electrons in the presence of magnetic field. Here the bag pressure is chosen such that in the absence of magnetic field and

We study high energy photon production from a quark-gluon plasma at finite baryon density. We find that the photon production spectrum from the quark-gluon plasma maintained at constant temperature is only mildly dependent on the quark chemical poten

We study the effect of hadronic interactions on the critical parameters in the entire phase space in a first-order phase transition for charge asymmetric matter (Q/B = 0.82/2.08) with zero net strangeness, which might be observed in Pb - Pb collision
