Full causal dissipative cosmologies with stiff matter
M. K. Mak, T. Harko
The general solution of the gravitational field equations for a full causal bulk viscous stiff cosmological fluid, with bulk viscosity coefficient proportional to the energy densit…
Quark stars admitting a one-parameter group of conformal motions
M. K. Mak, T. Harko
An exact analytical solution describing the interior of a charged strange quark star is found under the assumption of spherical symmetry and the existence of a one-parameter group…
Gravitational collapse of a Hagedorn fluid in Vaidya geometry
T. Harko
The gravitational collapse of a high-density null charged matter fluid, satisfying the Hagedorn equation of state, is considered in the framework of the Vaidya geometry. The genera…
Surface photon emissivity of bare strange stars
K. S. Cheng, T. Harko
We consider the bremsstrahlung surface photon emissivity of strange quark stars, by sistematically taking into account the effects of the multiple scatterings of the highly relativ…
