| Abstract: |
Strange quark stars are considered as a possible alternative to
neutron stars as compact objects (e.g. Weber 2003). A hot
compact star (a proto-neutron star or a strange star) born in a
supernova explosion or a remnant of neutron stars binary merger are
expected to rotate differentially and be important sources of
gravitational waves. We present results of the first relativistic
calculations of differentially rotating strange quark stars for broad
ranges of degree of differential rotation and maximum densities. Using
a highly accurate, relativistic code we show that rotation may cause a
significant increase of maximum allowed mass of strange stars, much
larger than in the case of neutron stars with the same degree of
differential rotation. Depending on the maximum allowed mass a massive
neutron star (strange star) can be temporarily stabilized by
differential rotation or collapse to a black hole. |
