Low-mass bare strange stars

Strange stars with low masses are suggested to exist in reality, the origin of which could be via accretion-induced collapse (AIC) of white dwarfs. Such a strange star is likely bare, and would thus spin very fast, even to a period of < 0.1 ms. Strange stars with low masses may differ from those with solar-masses in various astrophysical appearances. Observations to test this ``low-mass'' idea are proposed.
