ABYSS. IV. Identifying signatures of stellar youth in APOGEE spectra
Valentina Bonilla Villalobos, Marina Kounkel, Joseph Mullen +9
We develop a convolutional neural network classifier that performs spectroscopic identification of stellar youth (<40 Myr) in APOGEE spectra. This classifier is sensitive to severa…

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…
