Polarization Analysis of Ringdown Signals
Nicole Khusid, Will Farr, Max Isi
Merging binary black holes exhibit a ringdown phase in which they primarily emit gravitational waves in the shape of damped sinusoids corresponding to quasi-normal modes of the Ker…
Polka-dotted Stars II: Starspots and obliquities of Kepler-17 and Kepler-63
Sabina Sagynbayeva, Will M. Farr
Starspots trace stellar magnetic activity and influence both stellar evolution and exoplanet characterization. While occultation-based spot analyses have been applied to individual…
Rotation Periods for Stars in Open Cluster NGC 6819 From Kepler IRIS Light Curves
Sabina Sagynbayeva, Isabel L. Colman, Will M. Farr
We present an updated catalog of stellar rotation periods for the 2.5 Gyr open cluster NGC 6819 using the Kepler IRIS light curves from superstamp data. Our analysis uses Gaussian…
Polka-dotted Stars: a Hierarchical Model for Mapping Stellar Surfaces Using Occultation Light Curves and the Case of TOI-3884
Sabina Sagynbayeva, Will M. Farr, Brett Morris +1
We present StarryStarryProcess, a novel hierarchical Bayesian framework for mapping stellar surfaces using exoplanet transit light curves. While previous methods relied solely on s…
