| dc.description | A recent observation has shown that PSR B1257+12 could have quite small X-ray emitting area, only about 2000 m$^2$, 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 $R \simeq 0.6$ km and mass of $M \simeq 3\times10^{-4}\msun$. Such a low-mass quark star system may form in an accretion induced collapse process or a collision process of two quark stars. | |
