Searching for Stellar Activity Cycles using Flares II: The TESS CVZ
Tobin M. Wainer, Holland M. Stuart, Guadalupe Tovar Mendoza +3
The paper analyzes seven years of TESS short‑cadence data for over 14,000 stars in the Continuous Viewing Zone to detect long‑term changes in flare activity, identifying 17 stars w…
Gaia-GIC-1: An Evolving Catastrophic Planetesimal Collision Candidate
Anastasios Tzanidakis, James R. A. Davenport
We report the discovery of the optical dipper and low-luminosity infrared stellar transient Gaia20ehk (hereafter, Gaia-GIC-1), which is currently undergoing high-amplitude variabil…
Gas-depleted planet formation occurred in the four-planet system around the red dwarf LHS 1903
Thomas G. Wilson, Anna M. Simpson, Andrew Collier Cameron +173
Small exoplanet radii show two populations, referred to as super-Earths and sub-Neptunes, separated by a gap known as the radius valley. This may be produced by the removal of atmo…
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…
