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…
