Exoplanet-atmospheres at high spectral resolution: A CRIRES survey of hot-Jupiters
Ignas Snellen, Remco de Kok, Ernst de Mooij +3
Recently, we presented the detection of carbon monoxide in the transmission spectrum of extrasolar planet HD209458b, using CRIRES, the Cryogenic high-resolution Infrared Echelle Sp…
The Banana Project. III. Spin-orbit Alignment in the Long-period Eclipsing Binary NY Cephei
Simon Albrecht, Joshua Winn, Joshua Carter +2
Binaries are not always neatly aligned. Previous observations of the DI Her system showed that the spin axes of both stars are highly inclined with respect to one another and the o…
Orbital Orientations of Exoplanets: HAT-P-4b is Prograde and HAT-P-14b is Retrograde
Joshua N. Winn, Andrew W. Howard, John Asher Johnson +9
We present observations of the Rossiter-McLaughlin effect for two exoplanetary systems, revealing the orientations of their orbits relative to the rotation axes of their parent sta…
The Oblique Orbit of the Super-Neptune HAT-P-11b
Joshua N. Winn, John Asher Johnson, Andrew W. Howard +6
We find the orbit of the Neptune-sized exoplanet HAT-P-11b to be highly inclined relative to the equatorial plane of its host star. This conclusion is based on spectroscopic observ…
Hot Stars with Hot Jupiters Have High Obliquities
Joshua N. Winn, Daniel Fabrycky, Simon Albrecht +1
We show that stars with transiting planets for which the stellar obliquity is large are preferentially hot (T_eff > 6250 K). This could explain why small obliquities were observed…
The orbital motion, absolute mass, and high-altitude winds of exoplanet HD209458b
Ignas A. G. Snellen, Remco J. de Kok, Ernst J. W. de Mooij +1
For extrasolar planets discovered using the radial velocity method, the spectral characterization of the host star leads to a mass-estimate of the star and subsequently of the orbi…
The HAT-P-13 Exoplanetary System: Evidence for Spin-Orbit Alignment and a Third Companion
Joshua N. Winn, John Asher Johnson, Andrew W. Howard +6
We present new radial-velocity measurements of HAT-P-13, a star with two previously known companions: a transiting giant planet "b" with an orbital period of 3 days, and a more mas…
