Stellar obliquities in exoplanetary systems

SH Albrecht, RI Dawson, JN Winn - Publications of the …, 2022 - iopscience.iop.org
The rotation of a star and the revolutions of its planets are not necessarily aligned. This
article reviews the measurement techniques, key findings, and theoretical interpretations …

The occurrence and architecture of exoplanetary systems

JN Winn, DC Fabrycky - Annual Review of Astronomy and …, 2015 - annualreviews.org
The basic geometry of the Solar System—the shapes, spacings, and orientations of the
planetary orbits—has long been a subject of fascination as well as inspiration for planet …

The GAPS programme with HARPS-N at TNG-XIV. Investigating giant planet migration history via improved eccentricity and mass determination for 231 transiting …

AS Bonomo, S Desidera, S Benatti, F Borsa… - Astronomy & …, 2017 - aanda.org
We carried out a Bayesian homogeneous determination of the orbital parameters of 231
transiting giant planets (TGPs) that are alone or have distant companions; we employed …

Masses, radii, and orbits of small Kepler planets: the transition from gaseous to rocky planets

GW Marcy, H Isaacson, AW Howard… - The Astrophysical …, 2014 - iopscience.iop.org
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

S Albrecht, JN Winn, JA Johnson… - The Astrophysical …, 2012 - iopscience.iop.org
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 …

TESS transit timing of hundreds of hot Jupiters

ES Ivshina, JN Winn - The Astrophysical Journal Supplement …, 2022 - iopscience.iop.org
We provide a database of transit times and updated ephemerides for 382 planets based on
data from the NASA Transiting Exoplanet Survey Satellite (TESS) and previously reported …

Rotation and winds of exoplanet HD 189733 b measured with high-dispersion transmission spectroscopy

M Brogi, RJ De Kok, S Albrecht… - The Astrophysical …, 2016 - iopscience.iop.org
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 …

Physics of eclipsing binaries. II. Toward the increased model fidelity

A Prša, KE Conroy, M Horvat, H Pablo… - The Astrophysical …, 2016 - iopscience.iop.org
The precision of photometric and spectroscopic observations has been systematically
improved in the last decade, mostly thanks to space-borne photometric missions and ground …

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

HA Knutson, BJ Fulton, BT Montet, M Kao… - The Astrophysical …, 2014 - iopscience.iop.org
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 …
