Electron Cyclotron Maser Emission from Ejected Stellar Prominences on V374 Peg
C. E. Brasseur, M. M. Jardine, S. Daley-Yates +2
We investigate a possible origin for bursty radio emission observed on the active M dwarf V374 Peg, combining data-driven magnetic field modelling with archival radio light curves.…
Constraining the Coronal Properties of AB Dor in the Radio Regime
C. E. Brasseur, M. M. Jardine, G. A. J. Hussain
We present a multiwavelength study of AB Doradus, combining modelling that incorporates a spectropolarimetric magnetic field map with 8.4 GHz radio interferometry to measure the co…
Constraints on Stellar Flare Energy Ratios in the NUV and Optical From a Multiwavelength Study of GALEX and Kepler Flare Stars
C. E. Brasseur, Rachel A. Osten, Isaiah I. Tristan +1
We present a multiwavelength study of stellar flares on primarily G-type stars using overlapping time domain surveys in the near ultraviolet (NUV) and optical regimes. The NUV (GAL…
New Time-Resolved, Multi-Band Flares In The GJ 65 System With gPhoton
Scott W. Fleming, Chase Million, Rachel A. Osten +2
Characterizing the distribution of flare properties and occurrence rates is important for understanding habitability of M dwarf exoplanets. The GALEX space telescope observed the G…
TOI-811b and TOI-852b: New transiting brown dwarfs with similar masses and very different radii and ages from the TESS mission
Theron W. Carmichael, Samuel N. Quinn, George Zhou +17
We report the discovery of two transiting brown dwarfs (BDs), TOI-811b and TOI-852b, from NASA's Transiting Exoplanet Survey Satellite mission. These two transiting BDs have simila…
Complex Modulation of Rapidly Rotating Young M Dwarfs: Adding Pieces to the Puzzle
Maximilian N. Günther, David A. Berardo, Elsa Ducrot +37
New sets of young M dwarfs with complex, sharp-peaked, and strictly periodic photometric modulations have recently been discovered with Kepler/K2 (scallop shells) and TESS (complex…
Short Duration Stellar Flares in GALEX Data
C. E. Brasseur, Rachel A. Osten, Scott W. Fleming
We report on a population of short duration near-ultraviolet (NUV) flares in stars observed by the Kepler and GALEX missions. We analyzed NUV light curves of 34,276 stars observed…
