Polka-dotted Stars. II. Starspots and Obliquities of Kepler-17 and Kepler-63
Abstract
Abstract Starspots trace stellar magnetic activity and affect both stellar evolution and exoplanet characterization. While occultation-based spot studies have been applied to individual systems, comparative analyses remain limited. We apply the StarryStarryProcess Bayesian surface mapping framework to archival Kepler light curves of two planet hosts—Kepler-63 and Kepler-17—extending the validation established on TOI-3884 (Paper I). Across both systems, we infer characteristic spot radii of
