Hints of enhanced magnetic activity after the intermediate rotation period gap as traced by the chromospheric Ca ii infrared triplet
Diego Godoy-Rivera, Savita Mathur, Tyler Richey-Yowell +5
For low-mass stars (M < 1.4 Msun), the connection between stellar rotation and magnetic activity governs stellar spin-down, shapes the environments of their exoplanets, and provide…
Quantifying isochrone-based age uncertainties for rapidly rotating A-type stars
Simon J. Murphy, Anuj Gautam, Zachary R. Claytor
Accurate stellar ages and masses are essential for interpreting the demographics and physical properties of exoplanets, particularly for intermediate-mass, early-type stars where c…
The YREC Stellar Evolution Code: Public Data Release
Marc H. Pinsonneault, Jennifer L. van Saders, Lyra Cao +11
In this paper we present the public release of the Yale Rotating Evolution Code (YREC). YREC is a stellar evolution code that covers brown dwarfs and stars across a wide range of m…
200,000+ Deep Learning-inferred Periods of Stellar Variability from the All-Sky Automated Survey for Supernovae
Meir E. Schochet, Penelope Planet, Zachary R. Claytor +2
Stars exhibit a range of variability periods that depend on their mass, age, and evolutionary stage. For space-based photometric data, convolutional neural networks (CNNs) have dem…
The Impact of the MAST Data Archive
Richard A. Shaw, Jenny L. Novacescu, Sarah Weissman +31
The Barbara A. Mikulski Archive for Space Telescopes (MAST) hosts science-ready data products from over twenty NASA missions, plus community-contributed data collections, and other…
New Rotation Periods from the Kepler Bonus Background Light Curves
Zachary R. Claytor, Jamie Tayar
The Kepler field hosts the best studied sample of field star rotation periods. However, due to Kepler's large 4" pixels, many of its light curves are at high risk of contamination…
