论文摘要
我们介绍了与猎户座复合物相关的预元序列恒星的高能白光耀斑的检测，这是下一代过境调查（NGTS）的一部分。最高能量高达$ 5.2 \ times10^{35} $ erg，这些耀斑是迄今为止看到的一些最有活力的白光火光事件。我们已经使用了NGTS观察到耀斑和非力量恒星来测量4个MYR M0-M3星的平均耀斑发生率。我们还将结果与以前研究的结果相结合，以预测附近年轻协会的早期M星以上$ 1 \ times10^{35} $ ergs的平均速率。
We present the detection of high energy white-light flares from pre-main sequence stars associated with the Orion complex, observed as part of the Next Generation Transit Survey (NGTS). With energies up to $5.2\times10^{35}$ erg these flares are some of the most energetic white-light flare events seen to date. We have used the NGTS observations of flaring and non-flaring stars to measure the average flare occurrence rate for 4 Myr M0-M3 stars. We have also combined our results with those from previous studies to predict average rates for flares above $1\times10^{35}$ ergs for early M stars in nearby young associations.
