Quantifying the Effect of Short-timescale Stellar Activity Upon Transit Detection in M Dwarfs
Dana Clarice Yaptangco, Sarah Ballard, Jason Dittmann
M dwarf stars comprise 70-80% of the galaxy's stars and host most of its rocky planets. They also importantly differ from Sunlike stars in that they are "active" for billions of ye…

Plausibility of Capture into High-Obliquity States for Exoplanets in the M Dwarf Habitable Zone
Natalia M. Guerrero, Sarah A. Ballard, Yubo Su
For temperate exoplanets orbiting M dwarf hosts, the proximity of the habitable zone to the star necessitates careful consideration of tidal effects. Spin synchronization of the pl…
