Using rapid rotators as tracers of multiplicity statistics as a function of stellar density
Priyanka Cingirikonda, Marina Kounkel, Joseph Mullen
Recent works have identified that rapidly rotating stars are predominantly binaries with separations of a few to a few tenths of au. This is a crucial range of separation that is o…
