Starspots and spin-orbit alignment for Kepler cool host stars
Roberto Sanchis-Ojeda, Josh N. Winn, Daniel C. Fabrycky
The angle between the spin axis of the host star and the orbit of its planets (i.e., the stellar obliquity) is precious information about the formation and evolution of exoplanetar…
Kepler-47: A Transiting Circumbinary Multi-Planet System
Jerome A. Orosz, William F. Welsh, Joshua A. Carter +36
We report the detection of Kepler-47, a system consisting of two planets orbiting around an eclipsing pair of stars. The inner and outer planets have radii 3.0 and 4.6 times that o…
Alignment of the stellar spin with the orbits of a three-planet system
Roberto Sanchis-Ojeda, Daniel C. Fabrycky, Josh N. Winn +16
The Sun's equator and the planets' orbital planes are nearly aligned, which is presumably a consequence of their formation from a single spinning gaseous disk. For exoplanetary sys…
Measurements of Stellar Inclinations for Kepler Planet Candidates
Teruyuki Hirano, Roberto Sanchis-Ojeda, Yoichi Takeda +4
We present an investigation of spin-orbit angles for planetary system candidates reported by Kepler. By combining the rotational period inferred from the flux variation due t…
