FUMES IV: Optical and Far-ultraviolet Spectra of a Flare on the M Dwarf GJ 4334
Girish M. Duvvuri, J. Sebastian Pineda, Aylin García Soto +5
On 2017-09-20 we observed GJ 4334, an M5V dwarf rotating with a period of 23.5 days, simultaneously with both the Space Telescope Imaging Spectrograph aboard Hubble (1160 -- 1710 A…
Far-ultraviolet flares and variability of the young M dwarf AU Mic: a non-detection of planet c in transit at Lyman-alpha
Keighley E. Rockcliffe, Elisabeth R. Newton, Allison Youngblood +8
Atmospheric escape's potential to shape the exoplanet population motivates detailed observations of systems actively undergoing escape. AU Mic is a young and active M dwarf hosting…
Mind the Gap II: the near-UV fluxes of M dwarfs
Wei-Chun Jao, Allison Youngblood
Because of the continuous variations in mass, metallicity, and opacity, dwarf stars are distributed along the main sequence on optical and near-IR color-magnitude diagrams followin…
A Multiwavelength Survey of Nearby M dwarfs: Optical and Near-Ultraviolet Flares and Activity with Contemporaneous TESS, Kepler/K2, \textit{Swift}, and HST Observations
Rishi R. Paudel, Thomas Barclay, Allison Youngblood +14
We present a comprehensive multiwavelength investigation into flares and activity in nearby M~dwarf stars. We leverage the most extensive contemporaneous dataset obtained through t…
Degenerate interpretations of O spectral features in exoplanet atmosphere observations due to stellar UV uncertainties: a 3D case study with TRAPPIST-1e
Gregory Cooke, Dan Marsh, Catherine Walsh +1
TRAPPIST-1e is a potentially habitable terrestrial exoplanet orbiting an ultra-cool M Dwarf star and is a key target for observations with the James Webb Space Telescope (JWST). On…
Photochemically-produced SO in the atmosphere of WASP-39b
Shang-Min Tsai, Elspeth K. H. Lee, Diana Powell +82
Photochemistry is a fundamental process of planetary atmospheres that regulates the atmospheric composition and stability. However, no unambiguous photochemical products have been…
K2 Ultracool Dwarfs Survey. V. High superflare rates on rapidly rotating late-M dwarfs
Rishi R. Paudel, John E. Gizis, D. J. Mullan +4
We observed strong superflares (defined as flares with energy in excess of 10^33 erg) on three late-M dwarfs: 2MASS J08315742+2042213 (hereafter 2M0831+2042; M7 V), 2MASS J08371832…
