Grid search results comparing 43 RADYN model fits to the Hα and Hβ lines during the peak of the largest flare in our sample, which was observed with OSMOS from TIC 415508270 on 2020-12-09 at 5:52 UT. The electron beams that give the lowest RSS fits the observed spectra are characterized by low electron fluxes and energies of 1–2×1011 erg s−1 cm2 and 17–37 keV, respectively. The flare area coverage versus RSS value points are color-coded by increasing beam intensity, with select models labeled in gray. The model labeled in red signifies the favored models based on our data. -- astro-ph.SR

Short-Term Balmer Line Emission Variability in M Dwarfs

by Keith CowingFebruary 6, 2025February 6, 2025

M Dwarfs make up the majority of stars, offering an avenue for discovering exoplanets due to their smaller sizes. However, their magnetic activity poses challenges for exoplanet detection, characterization, and […]
