Starspots, spin-orbit misalignment, and active latitudes in the HAT-P-11 exoplanetary system
Roberto Sanchis-Ojeda, Joshua N. Winn
We present the analysis of 4 months of Kepler photometry of the K4V star HAT-P-11, including 26 transits of its "super-Neptune" planet. The transit data exhibit numerous anomalies…
The Transit Light Curve project. XIV. Confirmation of Anomalous Radii for the Exoplanets TrES-4b, HAT-P-3b, and WASP-12b
Tucker Chan, Mikael Ingemyr, Joshua N. Winn +4
We present transit photometry of three exoplanets, TrES-4b, HAT-P-3b, and WASP-12b, allowing for refined estimates of the systems' parameters. TrES-4b and WASP-12b were confirmed t…
Starspots and spin-orbit alignment in the WASP-4 exoplanetary system
Roberto Sanchis-Ojeda, Joshua N. Winn, Matthew J. Holman +3
We present photometry of 4 transits of the exoplanet WASP-4b, each with a precision of approximately 500 ppm and a time sampling of 40-60s. We have used the data to refine the esti…
