Role of Nonthermal Processes in the Quiescent and Active Millimeter Spectrum of a Young M Dwarf

Millimeter (mm) emission from F-M dwarfs (cool stars) primarily traces chromospheric activity, with thermal emission thought to dominate in quiescence. Despite the high chromospheric activity, the quiescent mm spectral fluence (mm- S ( ν )) of young (<1 Gyr) M dwarfs (dMs) remains largely unexplored...
