利用大空域多目标光纤光谱望远镜对早期型M0-M3矮星的光谱样本与开普勒观测结果进行了比较。研究发现，具有强色球发射的M矮星一般具有较大的耀斑活动。由开普勒测量得出的旋转周期与耀斑的大小、幂律分布指数和发射的等效宽度密切相关。在快速旋转的M矮星（自转周期< 20天）中，有明显的磁活动增强的趋势。
A sample of the Large Sky Area Multi-Object Fibre Spectroscopic Telescope spectra of early-type M0–M3 dwarfs is compared with Kepler observations. It is found that M dwarfs with strong chromospheric emission in have large flare activity in general. The rotational periods derived from the Kepler measurements have close correlations with the sizes of the flares, the power-law distribution index, and the equivalent widths of the emission. A clear trend exists for higher magnetic activities being detected in faster-rotating M dwarfs (rotation periods < 20 days).
