Searching for GEMS: Characterizing Six Giant Planets around Cool Dwarfs
Shubham Kanodia, Arvind F. Gupta, Caleb I. Canas +42
Transiting giant exoplanets around M-dwarf stars (GEMS) are rare, owing to the low-mass host stars. However, the all-sky coverage of TESS has enabled the detection of an increasing…
Time-dependent Stellar Flare Models of Deep Atmospheric Heating
Adam F. Kowalski, Joel C. Allred, Mats Carlsson
Optical flares have been observed from magnetically active stars for many decades; unsurprisingly, the spectra and temporal evolution are complicated. For example, the shortcomings…
TOI-2015b: A Warm Neptune with Transit Timing Variations Orbiting an Active mid M Dwarf
Sinclaire E. Jones, Gudmundur Stefansson, Kento Masuda +29
We report the discovery of a close-in () warm Neptune with clear transit timing variations (TTVs) orbiting the nearby ($d=47.3\:\mathrm{pc}…
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…
