  The possible existence of strange stars in the universe will help in the
understanding of various properties of quantum chromodynamics, like asymptotic
freedom and chiral symmetry restoration, which is otherwise very difficult to
prove in laboratory experiments. Strange star properties were calculated using
large $N_c$ approximation with built-in chiral symmetry restoration. A
relativistic Hartree Fock calculation was performed using the Richardson
potential as an interquark interaction. This potential has the asymptotic
freedom and a confinement-deconfinement mechanism built into it and the present
calculation employs an application of this potential with modified two scale
parameters $\Lambda$ and $\Lambda^{\prime}$, to find a new set of equations of
state for strange quark matter. The linear confinement string tension from
lattice calculations is 350 $MeV$ and the Coulomb -like part has the parameter
100 $MeV$ from deep inelastic scattering experiments. We also consider the
effect of temperature, $T$, on gluon mass in a simple way, in addition to the
usual density dependence, and find that the transition $T$ from hadronic matter
to strange matter is at 80 MeV, close to the 100 MeV estimated in litarature.
Therefore formation of strange stars may be the only signal for formation of
quark-gluon plasma with asymptotic freedom and chiral symmetry restoration and
this may be observable through many processes -such as for example through
delayed $\gamma$ ray afterglow.
