Searching for Stellar Activity Cycles using Flares II: The TESS CVZ
Tobin M. Wainer, Holland M. Stuart, Guadalupe Tovar Mendoza +3
Magnetic activity cycles provide a fundamental constraint on stellar dynamos, but remain difficult to identify beyond the Sun. However, recent studies have shown that flares offer…
First Temperature Profile of a Stellar Flare using Differential Chromatic Refraction
Riley Clarke, Federica Bianco, James R. A. Davenport +5
We present the first derivation of a stellar flare temperature profile from single-band photometry. Stellar flare DWF030225.574-545707.45129 was detected in 2015 by the Dark Energy…
Searching for Stellar Activity Cycles using Flares: The Short and Long Timescale Activity Variations of TIC-272272592
Tobin M. Wainer, James R. A. Davenport, Guadalupe Tovar Mendoza +2
We examine 4 years of Kepler 30-min data, and 5 Sectors of TESS 2-min data for the dM3 star KIC-8507979/TIC-272272592. This rapidly rotating (P=1.2 day) star has previously been id…
Detecting stellar flares in photometric data using hidden Markov models
J. Arturo Esquivel, Yunyi Shen, Vianey Leos-Barajas +5
We present a hidden Markov model (HMM) for discovering stellar flares in light curve data of stars. HMMs provide a framework to model time series data that are not stationary; they…
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…
