The Mass Dependence of Hα Emission and Stellar Spindown for Fully Convective M Dwarfs

The Astrophysical Journal
Fully convective M dwarfs typically remain rapidly rotating and magnetically active for billions of years, followed by an abrupt and mass-dependent transition to slow rotation and quiescence.
