摘要:

在斯隆数字巡天光谱中发现的39个激变变星的坐标、星等和光谱主要是在2006年获得的。其中,12个是在SDSS光谱之前鉴别的CV(GY Cnc、GO Com、ST LMi、NY Ser、MR Ser、QW Ser、EU UMa、IY UMa、HS 1340 +1524、RXJ1610.1+0352、Boo 1、Leo 5)。对七个系统(包括2005年的一个和2004年的另一个)进行了后续分光观测,从而对三个物体的轨道周期作出了估计。新的CV包括两个候选的高倾角,食系统,4个新的极地和三个系统,其光谱清楚地揭示了大气吸收线从底层的白矮星。

英文摘要:

Coordinates, magnitudes and spectra are presented for 39 cataclysmic variables found in Sloan Digital Sky Survey spectra that were primarily obtained in 2006. Of these, 12 were CVs identified prior to the SDSS spectra (GY Cnc, GO Com, ST LMi, NY Ser, MR Ser, QW Ser, EU UMa, IY UMa, HS1340+1524, RXJ1610.1+0352, Boo 1, Leo 5). Follow-up spectroscopic observations of seven systems (including one from year 2005 and another from year 2004) were obtained, resulting in estimates of the orbital periods for 3 objects. The new CVs include two candidates for high inclination, eclipsing systems, 4 new Polars and three systems whose spectra clearly reveal atmospheric absorption lines from the underlying white dwarf.
