论文摘要
M31N 2017-09A是一个古典的NOVA，在初次喷发后观察到了大约160天，在此期间，它发生了许多明亮的次要爆发。光曲线的特征是连续变化，每天的时间尺度上至少有0.5个幅度。喷发的下部包膜表明单个幂律可以描述下降率。喷发相对较长，$ t_2 = 111 $，$ t_3 = 153 $ days。
M31N 2017-09a is a classical nova and was observed for some 160 days following its initial eruption, during which time it underwent a number of bright secondary outbursts. The light-curve is characterized by continual variation with excursions of at least 0.5 magnitudes on a daily time-scale. The lower envelope of the eruption suggests that a single power-law can describe the decline rate. The eruption is relatively long with $t_2 = 111$, and $t_3 = 153$ days.
