Radio and Optical Flares on the dMe Flare Star EV Lac

Rachel A. Osten, Adam F. Kowalski, Suzanne Hawley +4

We present the results of a coordinated campaign to observe radio and optical stellar flares from the nearby M dwarf flare star EV~Lac. From a total of 27 hours of radio and 29 hou…

APO & SMARTS flare star campaign observations I. Blue wing asymmetries in chromospheric lines during mid M dwarf flares from simultaneous spectroscopic and photometric observation data

Yuta Notsu, Adam F. Kowalski, Hiroyuki Maehara +12

We conducted the time-resolved simultaneous optical spectroscopic and photometric observations of mid M dwarf flare stars YZ CMi, EV Lac, and AD Leo. Spectroscopic observations wer…

Modeling Stellar Surface Features on Subgiant Star with an M-dwarf Companion

Maria C. Schutte, Leslie Hebb, Simon Lowry +7

Understanding magnetic activity on the surface of stars other than the Sun is important for exoplanet analyses to properly characterize an exoplanet's atmosphere and to further cha…

Llamaradas Estelares: Modeling the Morphology of White-Light Flares

Guadalupe Tovar Mendoza, James R. A. Davenport, Eric Agol +2

Stellar variability is a limiting factor for planet detection and characterization, particularly around active M-type stars. Here we revisit one of the most active stars from the K…

The Mega-MUSCLES Spectral Energy Distribution Of TRAPPIST-1

David J. Wilson, Cynthia S. Froning, Girish M. Duvvuri +19

We present a 5A-100um Spectral Energy Distribution (SED) of the ultracool dwarf star TRAPPIST-1, obtained as part of the Mega-MUSCLES Treasury Survey. The SED combines ultraviolet…

10 Years of Stellar Activity for GJ 1243

James. R. A. Davenport, Guadalupe Tovar Mendoza, Suzanne L. Hawley

The flaring M4 dwarf GJ 1243 has become a benchmark for studying stellar flare and starspot activity thanks to the exceptional photometric monitoring archive from the Kepler missio…
