Characterizing the Cool KOIs IV: Kepler-32 as a prototype for the formation of compact planetary systems throughout the Galaxy
Jonathan J. Swift, John Asher Johnson, Timothy D. Morton +4
The Kepler space telescope has opened new vistas in exoplanet discovery space by revealing populations of Earth-sized planets that provide a new context for understanding planet fo…
Signals embedded in the radial velocity noise. Periodic variations in the tau Ceti velocities
Mikko Tuomi, Hugh R. A. Jones, James S. Jenkins +12
The abilities of radial velocity exoplanet surveys to detect the lowest-mass extra-solar planets are currently limited by a combination of instrument precision, lack of data, and "…
A lower radius and mass for the transiting extrasolar planet HAT-P-8b
L. Mancini, J. Southworth, S. Ciceri +10
Context. The extrasolar planet HAT-P-8 b was thought to be one of the more inflated transiting hot Jupiters. Aims. By using new and existing photometric data, we computed precise e…
On The Relative Sizes of Planets Within Kepler Multiple Candidate Systems
David R. Ciardi, Daniel C. Fabrycky, Eric B. Ford +5
We present a study of the relative sizes of planets within the multiple candidate systems discovered with the mission. We have compared the size of each planet to the size…
MOST Space Telescope Photometry of the 2010 January Transit of Extrasolar Planet HD80606b
Jessica E. Roberts, Jason W. Barnes, Jason F. Rowe +1
We present observations of the full January 2010 transit of HD80606b from the Canadian microsatellite, Microvariability and Oscillations of Stars (MOST). By employing a space-based…
Starspots and spin-orbit alignment for Kepler cool host stars
Roberto Sanchis-Ojeda, Josh N. Winn, Daniel C. Fabrycky
The angle between the spin axis of the host star and the orbit of its planets (i.e., the stellar obliquity) is precious information about the formation and evolution of exoplanetar…
On the Survivability and Metamorphism of Tidally Disrupted Giant Planets: the Role of Dense Cores
Shang-Fei Liu, James Guillochon, Douglas N. C. Lin +1
A large population of planetary candidates in short-period orbits have been found through transit searches. Radial velocity surveys have also revealed several Jupiter-mass planets…
Habitable-zone super-Earth candidate in a six-planet system around the K2.5V star HD 40307
Mikko Tuomi, Guillem Anglada-Escude, Enrico Gerlach +5
The K2.5 dwarf HD 40307 has been reported to host three super-Earths. The system lacks massive planets and is therefore a potential candidate for having additional low-mass planeta…
The Minimum-Mass Extrasolar Nebula: In-Situ Formation of Close-In Super-Earths
E. Chiang, G. Laughlin
Close-in super-Earths, with radii R = 2-5 R_Earth and orbital periods P < 100 days, orbit more than half, and perhaps nearly all Sun-like stars in the universe. We use this omnipre…
From dust to planetesimals: an improved model for collisional growth in protoplanetary disks
Pascale Garaud, Farzana Meru, Marina Galvagni +1
Planet formation occurs within the gas and dust rich environments of protoplanetary disks. Observations of these objects show that the growth of primordial sub micron sized particl…
Numerical modeling of the disruption of Comet D/1993 F2 Shoemaker-Levy 9 representing the progenitor by a gravitationally bound assemblage of randomly shaped polyhedra
Naor Movshovitz, Erik Asphaug, Donald Korycansky
We advance the modeling of rubble-pile solid bodies by re-examining the tidal breakup of comet Shoemaker-Levy 9, an event that occurred during a 1.33 Jupiter radii encounter with t…
GTC OSIRIS transiting exoplanet atmospheric survey: detection of sodium in XO-2b from differential long-slit spectroscopy
D. K. Sing, C. M. Huitson, M. Lopez-Morales +8
We present two transits of the hot-Jupiter exoplanet XO-2b using the Gran Telescopio Canarias (GTC). The time series observations were performed using long-slit spectroscopy of XO-…
Transit Timing Observations from Kepler: VII. Confirmation of 27 planets in 13 multiplanet systems via Transit Timing Variations and orbital stability
Jason H. Steffen, Daniel C. Fabrycky, Eric Agol +15
We confirm 27 planets in 13 planetary systems by showing the existence of statistically significant anti-correlated transit timing variations (TTVs), which demonstrates that the pl…
Coupled evolutions of the stellar obliquity, orbital distance, and planet's radius due to the Ohmic dissipation induced in a diamagnetic hot Jupiter around a magnetic T Tauri star
Yu-Ling Chang, Peter H. Bodenheimer, Pin-Gao Gu
We revisit the calculation of the Ohmic dissipation in a hot Jupiter presented in Laine et al. (2008) by considering more realistic interior structures, stellar obliquity, and the…
Three-dimensional atmospheric circulation of hot Jupiters on highly eccentric orbits
Tiffany Kataria, Adam P. Showman, Nikole K. Lewis +3
Of the over 800 exoplanets detected to date, over half are on non-circular orbits, with eccentricities as high as 0.93. Such orbits lead to time-variable stellar heating, which has…
Alignment of the stellar spin with the orbits of a three-planet system
Roberto Sanchis-Ojeda, Daniel C. Fabrycky, Josh N. Winn +16
The Sun's equator and the planets' orbital planes are nearly aligned, which is presumably a consequence of their formation from a single spinning gaseous disk. For exoplanetary sys…
GJ 581 update: Additional Evidence for a Super-Earth in the Habitable Zone
Steven S. Vogt, R. Paul Butler, Nader Haghighipour
We present an analysis of the significantly expanded HARPS 2011 radial velocity data set for GJ 581 that was presented by Forveille et al. (2011). Our analysis reaches substantiall…
The Lick-Carnegie Survey: A New Two-Planet System Around the Star HD 207832
Nader Haghighipour, R. Paul Butler, Eugenio J. Rivera +2
Keck/HIRES precision radial velocities of HD 207832 indicate the presence of two Jovian-type planetary companions in Keplerian orbits around this G star. The planets have minimum m…
New indication for a dichotomy in the interior structure of Uranus and Neptune from the application of modified shape and rotation data
N. Nettelmann, R. Helled, J. J. Fortney +1
Since the Voyager fly-bys of Uranus and Neptune, improved gravity field data have been derived from long-term observations of the planets' satellite motions, and modified shape and…
Doppler Signatures of the Atmospheric Circulation on Hot Jupiters
Adam P. Showman, Jonathan J. Fortney, Nikole K. Lewis +1
The meteorology of hot Jupiters has been characterized primarily with thermal measurements, but recent observations suggest the possibility of directly detecting the winds by obser…
