Analytic Description of the Rossiter-McLaughlin Effect for Transiting Exoplanets: Cross-Correlation Method and Comparison with Simulated Data
Teruyuki Hirano, Yasushi Suto, Atsushi Taruya +4
We obtain analytical expressions for the velocity anomaly due to the Rossiter- McLaughlin effect, for the case when the anomalous radial velocity is obtained by cross-correlation w…
First Evidence of a Retrograde Orbit of Transiting Exoplanet HAT-P-7b
Norio Narita, Bun'ei Sato, Teruyuki Hirano +1
We present the first evidence of a retrograde orbit of the transiting exoplanet HAT-P-7b. The discovery is based on a measurement of the Rossiter-McLaughlin effect with the Subaru…
Gifts from Exoplanetary Transits
Norio Narita
The discovery of transiting extrasolar planets has enabled us a number of interesting stduies. Transit photometry reveals the radius and the orbital inclination of transiting plane…
Improved Measurement of the Rossiter-McLaughlin Effect in the Exoplanetary System HD 17156
Norio Narita, Teruyuki Hirano, Bun'ei Sato +6
We present an improved measurement of the Rossiter-McLaughlin effect for the exoplanetary system HD 17156, based on radial-velocity data gathered with the Subaru 8.2m telescope thr…
On the Spin-Orbit Misalignment of the XO-3 Exoplanetary System
Joshua N. Winn, John Asher Johnson, Daniel Fabrycky +8
We present photometric and spectroscopic observations of the 2009 Feb. 2 transit of the exoplanet XO-3b. The new data show that the planetary orbital axis and stellar rotation axis…
