Planet-Planet Eclipse and the Rossiter-McLaughlin Effect of a Multiple Transiting System: Joint Analysis of the Subaru Spectroscopy and the Kepler Photometry
Teruyuki Hirano, Norio Narita, Bun'ei Sato +6
We report a joint analysis of the Rossiter-McLaughlin (RM) effect with Subaru and the Kepler photometry for Kepler Object of Interest (KOI) 94 system. The system comprises four tra…
A Common Proper Motion Stellar Companion to HAT-P-7
Norio Narita, Yasuhiro H. Takahashi, Masayuki Kuzuhara +51
We report that HAT-P-7 has a common proper motion stellar companion. The companion is located at arcsec to the east and estimated as an M5.5V dwarf based on its colors. W…
Obliquities of Hot Jupiter host stars: Evidence for tidal interactions and primordial misalignments
Simon Albrecht, Joshua N. Winn, John A. Johnson +10
We provide evidence that the obliquities of stars with close-in giant planets were initially nearly random, and that the low obliquities that are often observed are a consequence o…
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…
