Strange Stars: where are they?

Strange Stars, i.e., compact stars made of self-bound quark matter, are an intriguing alternative to "neutron" stars. To date there is not yet any convincing evidence either in favor or against their existence. I'll argue that if Strange Stars exist then the most massive compact stars in LMXB should be strange stars, and vice-versa, if these are not Strange Stars then Strange Stars do not exist. Models of thermal evolution of massive Strange Stars in LMXBs, in particular superbursting sources and SXRTs, could give an answer to this question.
