- 30 March 2017
The California-Kepler Survey (CKS) is an observational program developed to improve our knowledge of the properties of stars found to host transiting planets by NASA’s Kepler Mission. The improvement…
HAT-P-7: A RETROGRADE OR POLAR ORBIT, AND A THIRD BODY
- J. Winn, J. Johnson, M. Holman
- Physics, Geology
- 12 August 2009
We show that the exoplanet HAT-P-7b has an extremely tilted orbit, with a true angle of at least 86° with respect to its parent star's equatorial plane, and a strong possibility of retrograde motion.…
RE-EVALUATING WASP-12b: STRONG EMISSION AT 2.315 μm, DEEPER OCCULTATIONS, AND AN ISOTHERMAL ATMOSPHERE
- I. Crossfield, T. Barman, B. Hansen, I. Tanaka, T. Kodama
- Physics, Geology
- 17 October 2012
We revisit the atmospheric properties of the extremely hot Jupiter WASP-12b in light of several new developments. First, we present new narrowband (2.315 μm) secondary eclipse photometry, which…
CHARACTERIZING THE COOL KOIs. II. THE M DWARF KOI-254 AND ITS HOT JUPITER
- J. Johnson, J. Gazak, J. Lloyd
- Physics, Geology
- 30 November 2011
We report the confirmation and characterization of a transiting gas giant planet orbiting the M dwarf KOI-254 every 2.455239 days, which was originally discovered by the Kepler mission. We use radial…
FRIENDS OF HOT JUPITERS. IV. STELLAR COMPANIONS BEYOND 50 au MIGHT FACILITATE GIANT PLANET FORMATION, BUT MOST ARE UNLIKELY TO CAUSE KOZAI–LIDOV MIGRATION
- H. Ngo, H. Knutson, Ji Wang
- Geology, Physics
- 22 June 2016
Stellar companions can influence the formation and evolution of planetary systems, but there are currently few observational constraints on the properties of planet-hosting binary star systems. We…
ON THE SPIN–ORBIT MISALIGNMENT OF THE XO-3 EXOPLANETARY SYSTEM
- J. Winn, J. Johnson, M. Holman
- Geology, Physics
- 19 February 2009
We present photometric and spectroscopic observations of the 2009 February 2 transit of the exoplanet XO-3b. The new data show that the planetary orbital axis and stellar rotation axis are…
THE TRANSIT INGRESS AND THE TILTED ORBIT OF THE EXTRAORDINARILY ECCENTRIC EXOPLANET HD 80606b
We present the results of a transcontinental campaign to observe the 2009 June 5 transit of the exoplanet HD 80606b. We report the first detection of the transit ingress, revealing the transit…
Water Vapor and Clouds on the Habitable-zone Sub-Neptune Exoplanet K2-18b
- B. Benneke, I. Wong, J. Fraine
- Physics, GeologyAstrophysical Journal
- 10 September 2019
Results from the Kepler mission indicate that the occurrence rate of small planets (<3 R⊕) in the habitable zone of nearby low-mass stars may be as high as 80%. Despite this abundance, probing the…
