AbstractIn this paper, we study the cooling mechanisms of strange stars. We extend the study by introducing a new mechanism called the quark-quark bremsstrahlung on the stellar surface. This bremsstrahlung radiation is 10-5 times weaker than the blackbody radiation. However, this mechanism becomes the dominant cooling mechanism when the surface temperature is lower than 10 9K because of the extremely high density of strange star near the surface will suppress the blackbody radiation exponentially. The luminosity of the emitted bremsstrahlung radiation also depends on the opacity of the electron layer as the radiation is scattered by electrons on the strange star's surface. We suggest that the thermal bremsstrahlung spectrum is the key signature to differentiate strange stars from neutron stars.
