Complete high-energy census of the cool stellar neighbors

TESS is soon to boost the number of known exoplanetary systems especially withEarthsize planets around nearby, small (Mtype) stars. Irradiation by thestars. highenergy emission can severely affect the planet atmospheres which,therefore, cannot be characterized without knowing the host star Xray/UV (XUV)properties. These emissions are also key diagnostics of stellar dynamos and atracer of spin evolution in fully convective stars. Yet, >40% of the M dwarfswithin only 10pc have no tight limit on their Xray emission. We, thus, proposean XUV XMMNewton survey of all 41 still Xray undetected early to midM dwarfswithin 10pc, providing the ultimate constraint on M dwarf XUV emission as vitalinput to models of planetary atmospheres, dynamos and spin evolution. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
