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…
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…
The M-dwarf Ultraviolet Spectroscopic Sample I. Determining Stellar Parameters for Field Stars
J. Sebastian Pineda, Allison Youngblood, Kevin France
Accurate stellar properties are essential for precise stellar astrophysics and exoplanetary science. In the M-dwarf regime, much effort has gone into defining empirical relations t…
FUMES. II. Ly Reconstructions of Young, Active M Dwarfs
Allison Youngblood, J. Sebastian Pineda, Kevin France
The HI Ly (1215.67 $\unicode{xC5}$) emission line dominates the far-UV spectra of M dwarf stars, but strong absorption from neutral hydrogen in the interstellar medium makes obs…
The Far Ultraviolet M-dwarf Evolution Survey. I. The Rotational Evolution of High-Energy Emissions
J. Sebastian Pineda, Allison Youngblood, Kevin France
M-dwarf stars are prime targets for exoplanet searches because of their close proximity and favorable properties for both planet detection and characterization. However, the potent…
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…
