Optical Spectropolarimetry of Three microquasars, Cyg X-1, LS5039, LSI +61d303

摘要：

We present optical spectropolarimetric observations of three microquasars, Cyg X-1, LS 5039 and LS I +61d 303. For Cyg X-1, the observed polarization shows time variation correlated with the orbital phase. For LS 5039, there is no evidence of intrinsic polarization. For LS I +61d 303, the result is consistent with that of 2005 Jan, Oct and Nov, except for the systematic decrease in the intrinsic polarization and in the EWs of the Ha emission line.
