Atmospheric Escape From Three Terrestrial Planets in the L 98-59 System
Emeline F. Fromont, John P. Ahlers, Laura N. R. do Amaral +6
A critically important process affecting the climate evolution and potential habitability of an exoplanet is atmospheric escape, in which high-energy radiation from a star drives t…
The Variable Detection of Atmospheric Escape around the young, Hot Neptune AU Mic b
Keighley E. Rockcliffe, Elisabeth R. Newton, Allison Youngblood +5
Photoevaporation is a potential explanation for several features within exoplanet demographics. Atmospheric escape observed in young Neptune-sized exoplanets can provide insight in…
Enabling Stellar Flare Science in the Roman Galactic Bulge Survey: Cadence, Filters, and the Read-Out Strategy Matter
Guadalupe Tovar Mendoza, Robert F. Wilson, Allison Youngblood +4
As was discovered with other wide field, precise imagers, the stable photometry necessary for the microlensing surveys is well-suited to general stellar astrophysics, including ste…
The MUSCLES Extension for Atmospheric and Transmission Spectroscopy: UV and X-ray Host-star Observations for JWST ERS & GTO Targets
Patrick R. Behr, Kevin France, Alexander Brown +8
X-ray through infrared spectral energy distributions (SEDs) are essential for understanding a star's effect on exoplanet atmospheric composition and evolution. We present a catalog…
Coronal Heating as Determined by the Solar Flare Frequency Distribution Obtained by Aggregating Case Studies
James Paul Mason, Alexandra Werth, Colin G. West +999
Flare frequency distributions represent a key approach to addressing one of the largest problems in solar and stellar physics: determining the mechanism that counter-intuitively he…
Three long period transiting giant planets from TESS
Rafael Brahm, Solène Ulmer-Moll, Melissa J. Hobson +52
We report the discovery and orbital characterization of three new transiting warm giant planets. These systems were initially identified as presenting single transit events in the…
Observations of GRB 230307A by TESS
Michael M. Fausnaugh, Rahul Jayaraman, Roland Vanderspek +13
We present the TESS light curve of GRB 230307A. We find two distinct components: a bright, prompt optical component at the time of the Fermi observation that peaked at TESS magnitu…
A High-Eccentricity Warm Jupiter Orbiting TOI-4127
Arvind F. Gupta, Jonathan M. Jackson, Guillaume Hebrard +36
We report the discovery of TOI-4127 b, a transiting, Jupiter-sized exoplanet on a long-period ( d), high-eccentricity orbit around a late F-type…
Coronal X-Ray Emission from Nearby, Low-Mass, Exoplanet Host Stars Observed by the MUSCLES and Mega-MUSCLES HST Treasury Survey Projects
Alexander Brown, P. Christian Schneider, Kevin France +8
The high energy X-ray and ultraviolet (UV) radiation fields of exoplanet host stars play a crucial role in controlling the atmospheric conditions and the potential habitability of…
Disentangling Stellar and Airglow Emission Lines from HST-COS Spectra
Fernando Cruz Aguirre, Allison Youngblood, Kevin France +1
H I Ly (1215.67 Å) and the O I triplet (1302.17, 1304.86, and 1306.03 Å) are bright far-ultraviolet (FUV) emission lines that trace the stellar chromosphere. Observations of ste…
A Second Earth-Sized Planet in the Habitable Zone of the M Dwarf, TOI-700
Emily A. Gilbert, Andrew Vanderburg, Joseph E. Rodriguez +29
We report the discovery of TOI-700 e, a 0.95 R planet residing in the Optimistic Habitable Zone (HZ) of its host star. This discovery was enabled by multiple years of moni…
The transmission spectrum of the potentially rocky planet L 98-59 c
Thomas Barclay, Kyle B. Sheppard, Natasha Latouf +32
We present observations of the 1.35+/-0.07 Earth-radius planet L 98-59 c, collected using Wide Field Camera 3 on the Hubble Space Telescope. L 98-59 is a nearby (10.6 pc), bright (…
