Abstract
In this study, we derive the magnetized Taub adiabat (TA) equation from the hydrodynamic conservation conditions. For the conversion of one phase to other the combustion adiabat (CA) equation is the same as the TA equation, only the equation of state (EoS) of the upstream phase is different from that of the EoS of the downstream phase. We employ the magnetized CA equations to study the evolution of a magnetized neutron star to a magnetized quark star. The pressure of the burnt quark matter has a maximum, which indicates a bound on the maximum mass of the quark star. The central density of the neutron star and the angle between the rotation axis and the magnetic axis (defined as the tilt angle) are seen to be significant in determining the magnetic field, and the tilt of the quark star. The magnetic field and the tilt of the quark star can have important observational significance and can help in understanding the physics at high density and strong magnetic field.
