Quantifying the Contamination of TESS Ecliptic-Plane Light Curves by Minor Planets
Ben Cassese, Justin Vega, Daniel A. Yahalomi +6
Though missions devoted to time series photometry focus primarily on targets far beyond the solar system, their observations can be contaminated by foreground minor planets, especi…
ChronoFlow: A Data-Driven Model for Gyrochronology
Phil R. Van-Lane, Joshua S. Speagle, Gwendolyn M. Eadie +6
Gyrochronology is a technique for constraining stellar ages using rotation periods, which change over a star's main sequence lifetime due to magnetic braking. This technique shows…
Measuring Long Stellar Rotation Periods (>10 days) from TESS FFI Light Curves is Possible: An Investigation Using TESS and ZTF
Soichiro Hattori, Ruth Angus, Daniel Foreman-Mackey +3
The rotation period of a star is an important quantity that provides insight into its structure and state. For stars with surface features like starspots, their periods can be infe…
A Data-Driven M Dwarf Model and Detailed Abundances for 17,000 M Dwarfs in SDSS-V
Aida Behmard, Melissa K. Ness, Andrew R. Casey +6
The cool temperatures of M dwarf atmospheres enable complex molecular chemistry, making robust characterization of M dwarf compositions a long-standing challenge. Recent modificati…
Exoplanet Occurrence Rate with Age for FGK Stars in Kepler
Maryum Sayeed, Ruth Angus, Travis Berger +5
We measure exoplanet occurrence rate as a function of isochrone and gyrochronology ages using confirmed and candidate planets identified in Q1-17 DR25 Kepler data. We employ Kepler…
zoomies: A tool to infer stellar age from vertical action in Gaia data
Sheila Sagear, Adrian M. Price-Whelan, Sarah Ballard +4
Stellar age measurements are fundamental to understanding a wide range of astronomical processes, including Galactic dynamics, stellar evolution, and planetary system formation. Ho…
