The Discovery of HD 37605c and a Dispositive Null Detection of Transits of HD 37605b
Sharon Xuesong Wang, Jason T. Wright, William Cochran +15
We report the radial-velocity discovery of a second planetary mass companion to the K0 V star HD 37605, which was already known to host an eccentric, P~55 days Jovian planet, HD 37…
Revisiting rho 1 Cancri e: A New Mass Determination Of The Transiting super-Earth
Michael Endl, Paul Robertson, William D. Cochran +6
We present a mass determination for the transiting super-Earth rho 1 Cancri e based on nearly 700 precise radial velocity (RV) measurements. This extensive RV data set consists of…
Kepler-36: A Pair of Planets with Neighboring Orbits and Dissimilar Densities
Joshua A. Carter, Eric Agol, William J. Chaplin +43
In the Solar system the planets' compositions vary with orbital distance, with rocky planets in close orbits and lower-density gas giants in wider orbits. The detection of close-in…
A Second Giant Planet in 3:2 Mean-Motion Resonance in the HD 204313 System
Paul Robertson, J. Horner, Robert A. Wittenmyer +7
We present 8 years of high-precision radial velocity (RV) data for HD 204313 from the 2.7 m Harlan J. Smith Telescope at McDonald Observatory. The star is known to have a giant pla…
The McDonald Observatory Planet Search: New Long-Period Giant Planets, and Two Interacting Jupiters in the HD 155358 System
Paul Robertson, Michael Endl, William D. Cochran +7
We present high-precision radial velocity (RV) observations of four solar-type (F7-G5) stars - HD 79498, HD 155358, HD 197037, and HD 220773 - taken as part of the McDonald Observa…
Transit Timing Observations from Kepler: III. Confirmation of 4 Multiple Planet Systems by a Fourier-Domain Study of Anti-correlated Transit Timing Variations
Jason H. Steffen, Daniel C. Fabrycky, Eric B. Ford +45
We present a method to confirm the planetary nature of objects in systems with multiple transiting exoplanet candidates. This method involves a Fourier-Domain analysis of the devia…
Transit Timing Observations from Kepler: II. Confirmation of Two Multiplanet Systems via a Non-parametric Correlation Analysis
Eric B. Ford, Daniel C. Fabrycky, Jason H. Steffen +48
We present a new method for confirming transiting planets based on the combination of transit timingn variations (TTVs) and dynamical stability. Correlated TTVs provide evidence th…
