天琴座中两个新的激变变星

Two New Cataclysmic Variables in Lyra

D. V. Denisenko

摘要:

我报告发现的两个激变变量在同一领域的天琴座最初确定的星等在USNO-B1.0目录和Palomar图像。在莫斯科收集的300多张照片上分析了历史光变曲线,涵盖了35年的观测。其中一颗星USNO-B1.0 1320-0390658在B~20到B=15.2之间有相当频繁的爆发,可能是UGSS型矮新星。另一颗变星USNO-B1. 01321 -0397655在1993年只观测到一次爆发,爆发范围从R~19到I=11.8,是UGWZ矮新星或复发新星。在这两种情况下,它的下一次爆发都可能在最近的将来发生。

英文摘要:

I report on the discovery of two cataclysmic variables in the same field in Lyra originally identified from their magnitudes in USNO-B1.0 catalogue and Palomar images. The historical light curves were analyzed on 300+ photographic plates from Moscow collection covering 35 years of observations. One of two stars, USNO-B1.0 1320-0390658, is showing rather frequent outbursts from B~20 to B=15.2 and is likely a dwarf nova of UGSS subtype. The other variable, USNO-B1.0 1321-0397655, has only one observed outburst in 1993 from R~19 to I=11.8 and is either a UGWZ dwarf nova or a recurrent nova. In both cases its next outburst can occur in the nearest future.
