Scientific paper
We carried out spectro-polarimetry of three outburst objects, CI Cam, Nova Sgr 1998, and U Sco. Although we were not able to detect the evidence of the intrinsic polarization for the former two stars, we succeeded in confirming the existence of intrinsic polarization for the last one, U Sco. U Sco showed de-polarization effect on emission lines. It also showed rapid variation of the continuum polarization. Its behavior resembles that observed for a classical nova, V1974 Cyg, although the time-scale of variation differs between two novae.
