Abstract

Stellar atmospheres encompass an abundance of waves and oscillations. This includes those associated with flares. Oscillatory and pulsating signatures, commonly known as quasi-periodic pulsations (QPPs), are observed at many wavelengths during both solar and stellar flares. These oscillatory phenomena travel on magnetic field lines in the star's atmosphere and can provide insight into the astrophysical processes of flares. We present a preliminary study of flare oscillations in a nearby, active M dwarf star. We use high cadence Swift (~1 sec, UV) data to measure QPP properties and place constraints on the fundamental processes driving flares at different layers of the stellar atmosphere. We present preliminary results to be incorporated with high-cadence TESS 20-second flare data for future studies.
