A Pilot Survey of an M Dwarf Flare Star with Swift's UV Grism
Shashank Chavali, Allison Youngblood, Rishi R. Paudel +5
The near-ultraviolet (NUV) spectral region is a useful diagnostic for stellar flare physics and assessing the energy environment of young exoplanets, especially as relates to prebi…
X-ray Emission from the Exoplanet Hosting LTT 1445 Triple Star System
Alexander Brown, Cynthia S. Froning, Allison Youngblood +5
JWST will be able to observe the atmospheres of rocky planets transiting nearby M dwarfs. The M dwarf triple star system LTT 1445, at a distance of 6.86 pc, hosts some of the neare…
The Mouse that Squeaked: A small flare from Proxima Cen observed in the millimeter, optical, and soft X-ray with Chandra and ALMA
Ward S. Howard, Meredith A. MacGregor, Rachel Osten +10
We present millimeter, optical, and soft X-ray observations of a stellar flare with an energy squarely in the regime of typical X1 solar flares. The flare was observed from Proxima…
The Extreme-ultraviolet Stellar Characterization for Atmospheric Physics and Evolution (ESCAPE) Mission: Motivation and Overview
K. France, B. Fleming, A. Youngblood +4
The Extreme-ultraviolet Stellar Characterization for Atmospheric Physics and Evolution (ESCAPE) mission is an astrophysics Small Explorer employing ultraviolet spectroscopy (EUV: 8…
Effects of UV stellar spectral uncertainty on the chemistry of terrestrial atmospheres
D. J. Teal, Eliza M. -R. Kempton, Sandra Bastelberger +2
The upcoming deployment of JWST will dramatically advance our ability to characterize exoplanet atmospheres, both in terms of precision and sensitivity to smaller and cooler planet…
Intrinsic Lyman alpha Profiles of High-Velocity G, K, and M Dwarfs
Allison Youngblood, J. Sebastian Pineda, Thomas Ayres +5
Observations of H I Lyman alpha, the brightest UV emission line of late-type stars, are critical for understanding stellar chromospheres and transition regions, modeling photochemi…
