摘要:

BZ Uma是一颗激变变星,自1968年发现以来,研究人员一直无法对其进行具体的分类。它的爆发和光谱特性与U宝石级矮新星和中间极相一致。我们提出了新的光度和偏振测量最近的爆发,包括第一次检测到的超级爆发的系统。对这些数据和过去40年来爆发的档案数据进行统计分析,提出了BZ UMa是一颗非磁性的U宝石类SU-UMa亚类矮新星的情况。

英文摘要:

BZ UMa is a cataclysmic variable star whose specific classification has eluded researchers since its discovery in 1968. It has outburst and spectral properties consistent with both U Gem class dwarf novae and intermediate polars. We present new photometric and polarimetric measurements of recent outbursts, including the first detected superoutburst of the system. Statistical analysis of these and archival data from outbursts over the past 40 years present a case for BZ UMa as a non-magnetic, U Gem class, SU-UMa subclass dwarf novae.
