NICER observation list: Target ID 567104

We propose to obtain NICER X-ray data of four nearby active mid-M dwarfs simultaneously with the Atacama Large Millimeter Array radio and the Neil Gehrels Swift Observatory UV data. These stars are spectral analogues of another flaring mid-M dwarf with a planetary system - Proxima Cen - and span a wider range of ages and activity levels. Such data will enable us a) understand the physical mechanism associated with M dwarf flares, b) examine if the correlation between millimeter and UV emission found in a previous study of Proxima Cen flare extends into X-ray wavelength and is a universal property of mid-M dwarfs regardless of age and activity level. Our results will be significant inputs to models that estimate the impacts of strong flares on the atmospheres of planets orbiting M dwarfs.
