Low-mass stellar astrophysics has undergone a renaissance over the past two decades. Large surveys have provided statistical samples of these small, dim stars, and the ubiquity of small planets around low-mass stars has reignited interest in their fundamental properties and space weather. In this talk, I will present my work to understand the smallest stars and their stellar and exoplanetary companions. First, I will describe the magnetic activity of M dwarf stars revealed using a large sample of spectroscopically confirmed, high proper motion white dwarf-M dwarf binaries.
