论文摘要
我们已经从12个活性G，K和M矮人的光曲线分析中搜索了耀斑。作为数据的来源，我们从2000 - 2020年使用了基于地面的观测值，该数据库ASAS，SuperWasp，KWS。可能是耀斑的低振幅亮度（Delta v <0.25 mag）的事件已显示为11颗恒星。在K矮人上发现了大量此类亮度。在一颗G恒星的光曲线和两个M矮人的光曲线上检测到V-Magnudes增加到0.5 mag或更多MAG的事件。对于三个耀斑，我们可以随着时间的推移效仿他们的发展。我们估计了这些耀斑的持续时间；他们持续了一个多小时，但不到3个小时。在大多数情况下，我们无法确定建议的耀斑的寿命，但是我们认为，在几分钟的时间内，所研究的凉爽矮人上的大多数可能的耀斑都是短暂的。
We have carried out a search for flares from the analysis of light curves for 12 active G, K, and M dwarfs. As sources of data we used ground-based observations in 2000-2020 from the photometric databases ASAS, SuperWASP, KWS. Events of low-amplitude brightening (Delta V < 0.25 mag), which possibly could be flares, were revealed for 11 stars. A large number of such increases in brightness were found on K dwarfs. Events of increasing in V-magnitudes to 0.5 mag or more were detected on light curves of one G star, BE Cet, and two M dwarfs. For three flares we could follow their development with time. We have estimated the duration of these flares; they lasted more than an hour, but less than 3 hours. In most cases we could not determine a lifetime of the suggested flares, but we believe that most of the probable flares on the investigated cool dwarfs are short-lived, on the order of several minutes.
