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…
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…
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…
Model Choice Matters for Age Inference on the Red Giant Branch
Leslie M. Morales, Jamie Tayar, Zachary R. Claytor
Galactic archaeology relies on accurate stellar parameters to reconstruct the galaxy's history, including information on stellar ages. While the precision of data has improved sign…
Magnetic activity evolution of solar-like stars: II. -Ro evolution of Kepler main-sequence targets
Savita Mathur, Angela R. G. Santos, Zachary R. Claytor +16
There is now a large sample of stars observed by the Kepler satellite with measured rotation periods and photometric activity index . We use this data, in conjunction w…
