NGC 1901: A new benchmark cluster for gyrochronology in the TESS Southern continuous viewing zone

Mara Bernizzoni, Timothy R. Bedding, Prasad Mani +5

We use Gaia DR3 astrometry and TESS time-series photometry to study NGC 1901, a sparse open cluster in the TESS Southern continuous viewing zone, that has been neglected due to its…

Improving the Physical Interpretability of Gaussian Processes in Stellar Activity Modeling: A Study Case on Photometric Variability Among Stellar Clusters

Leslie Moranta, Jonathan Gagné, Jacqueline K. Faherty +12

Gaussian Processes (GPs) are widely used to model stellar variability in photometric surveys, but a statistically successful fit does not guarantee that the inferred hyperparameter…

Theia 456: Tidally Shredding an Open Cluster

Kyle R. Tregoning, Jeff J. Andrews, Marcel A. Agüeros +4

The application of clustering algorithms to the Gaia astrometric catalog has revolutionized our census of stellar populations in the Milky Way, including the discovery of many new,…

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…

The Factory and the Beehive. V. Chromospheric and Coronal Activity and Its Dependence on Rotation in Praesepe and the Hyades

Alejandro Núñez, M. A. Agüeros, J. L. Curtis +6

Low-mass (< 1.2 Solar mass) main-sequence stars lose angular momentum over time, leading to a decrease in their magnetic activity. The details of this rotation-activity relation re…

Wrinkles in Time -- I: Rapid Rotators Found in High Eccentricity Orbits

Rayna Rampalli, Amy Smock, Elisabeth R. Newton +2

Recent space-based missions have ushered in a new era of observational astronomy, where high-cadence photometric light curves for thousands to millions of stars in the solar neighb…
