PSR B1257+12: a quark star with planets?

摘要：

A recent observation has shown that PSR B1257+12 could have quite small X-ray emitting area, only about 2000m<2>, which is more than three orders smaller than the canonical polar cap size. We suggest here that PSR B1257+12 could be a low-mass quark star with radius of R??0.6km and mass of M??3×10<-4>M??. Such a low-mass quark star system may form in an accretion induced collapse process or a collision process of two quark stars.
