Masses, radii, and orbits of small Kepler planets: the transition from gaseous to rocky planets
We report on the masses, sizes, and orbits of the planets orbiting 22 Kepler stars. There are
49 planet candidates around these stars, including 42 detected through transits and 7 …

Obliquities of hot Jupiter host stars: Evidence for tidal interactions and primordial misalignments
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 of …

Rotation and winds of exoplanet HD 189733 b measured with high-dispersion transmission spectroscopy
Giant exoplanets orbiting very close to their parent star (hot Jupiters) are subject to tidal
forces expected to synchronize their rotational and orbital periods on short timescales (tidal …

Hot stars with hot Jupiters have high obliquities
JN Winn, D Fabrycky, S Albrecht… - The Astrophysical …, 2010 - iopscience.iop.org
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 in …

Friends of hot Jupiters. I. A radial velocity search for massive, long-period companions to close-in gas giant planets
In this paper we search for distant massive companions to known transiting gas giant
planets that may have influenced the dynamical evolution of these systems. We present new …
