MASTER OT J190519 .41+301524.4:VY Scl型的新突变变量

MASTER OT J190519.41+301524.4: New Eclipsing Cataclysmic Variable of VY Scl Type

F. Martinelli, D. V. Denisenko

摘要:

MASTER OT J190519.41+301524.4在2014年3月被望远镜机器人的移动天文系统发现为15.7米的光学瞬变。我们报告了2015年6月至7月在Lajatico天文中心进行的该变量的光度观测结果。光变曲线显示出深V形的日食,振幅为两个星等。轨道周期为0.129694 d(3.113 h)。根据观测资料和轨道曲线的形状,我们认为MASTER OT J190519.41+301524.4是一颗新的VY Scl型激变变星(“反新星”),倾角接近90度。

英文摘要:

MASTER OT J190519.41+301524.4 was discovered as an optical transient of 15.7m by the Mobile Astronomical System of TElescope-Robots in March 2014. We report the results of photometric observations of this variable performed at Lajatico Astronomical Center in June-July 2015. The light curve is showing deep V-shaped eclipses with an amplitude of two magnitudes. The orbital period was determined to be 0.129694 d (3.113 h). Based on the archival observations and the shape of the orbital curve we suggest that MASTER OT J190519.41+301524.4 is a new cataclysmic variable of VY Scl type ("anti-nova") with an inclination angle close to 90 deg.
