摘要
We study the effect of dark matter heating on the temperature of typical strange star (SS hereafter) (M = 1.4 M-aS (TM), R = 10 km) in normal phase (NSS hereafter) and in a possible existing colour-flavour locked (CFL)phase (CSS hereafter). For NSS, the influence of dark matter heating is ignored until roughly 10(7) yr. After 10(7) yr, the dark matter heating is dominant that significantly delays the star cooling, which maintains a temperature much higher than that predicted by standard cooling model for old stars. Especially for CSS, the emissivity of dark matter will play a leading role after roughly 10(4) yr, which causes the temperature to rise. This leads to the plateau of surface temperature appearing in similar to 10(6.5) yr which is earlier than that of NSS (similar to 10(7) yr).
