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…
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…
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…
Evidence of Truly Young high- Dwarf Stars
Yuxi Lu, Isabel L. Colman, Maryum Sayeed +14
The existence of high- stars with inferred ages < 6 Gyr has been confirmed recently with large spectroscopic and photometric surveys. However, stellar mergers or binary interact…
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…
Methods for the detection of stellar rotation periods in individual TESS sectors and results from the Prime mission
Isabel L. Colman, Ruth Angus, Trevor David +3
For ongoing studies of the role of rotation in stellar evolution, we require large catalogs of rotation periods for testing and refining gyrochronology. While there is a wealth of…
Transiting exoplanets from the CoRoT space mission XXV. CoRoT-27b: a massive and dense planet on a short-period orbit
H. Parviainen, D. Gandolfi, M. Deleuil +36
We report the discovery of a massive and dense transiting planet CoRoT-27b on a 3.58 day orbit around a 4.2 Gyr-old G2 star. The planet candidate was identified from the CoRoT phot…
