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 "…

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…

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…

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…

The EVIL-MC Model for Ellipsoidal Variations of Planet-Hosting Stars and Applications to the HAT-P-7 System

Brian K. Jackson, Nikole K. Lewis, Jason W. Barnes +3

We present a new model for Ellipsoidal Variations Induced by a Low-Mass Companion, the EVIL-MC model. We employ several approximations appropriate for planetary systems to substant…

Circumbinary Planet Formation in the Kepler-16 system. I. N-body Simulations

Stefano Meschiari

The recently discovered circumbinary planets (Kepler-16 b, Kepler-34 b, Kepler-35 b) represent the first direct evidence of the viability of planet formation in circumbinary orbits…
