Complete high-energy census of the cool stellar neighbors

New facilities like TESS will soon boost the number of known terrestrial planetsaround M stars. Stellar Xrays can severely affect planetary atmospheres, butmore than 40% of the M dwarfs within only 10pc lack appropriate data. We, thus,propose to continue our Xray and UV XMMNewton survey of all 37 still Xrayundetected M0M4 dwarfs within 10pc. This 925ks Fulfil Project will provide theultimate constraint on M dwarf Xray luminosity function, plasma temperature,short timescale variability and UV spectral energy distribution, vital input tomodels of planetary atmospheres, dynamos and spin evolution, as a legacy forfuture stellar/exoplanetary modeling work. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
