Pervasive Orbital Eccentricities Dictate the Habitability of Extrasolar Earths
Ryosuke Kita, Frederic A. Rasio, Genya Takeda
The long-term habitability of Earth-like planets requires low orbital eccentricities. A secular perturbation from a distant stellar companion is a very important mechanism in excit…
Two Jupiter-Mass Planets Orbiting HD 154672 and HD 205739
Mercedes Lopez-Morales, R. Paul Butler, Debra A. Fischer +6
We report the detection of the first two planets from the N2K Doppler planet search program at the Magellan telescopes. The first planet has a mass of M sin i = 4.96 M_Jup and is o…
On The Origins Of Eccentric Close-in Planets
Soko Matsumura, Genya Takeda, Fred Rasio
Strong tidal interaction with the central star can circularize the orbits of close-in planets. With the standard tidal quality factor Q of our solar system, estimated circularizati…
Induced Kozai Migration and Formation of Close-in Planets in Binaries
Genya Takeda, Ryosuke Kita, Frederic A. Rasio
Many recent observational studies have concluded that planetary systems commonly exist in multiple-star systems. At least ~20%, and presumably a larger fraction of the known extras…
Secular Evolution of Planetary Systems in Binaries
Genya Takeda, Ryosuke Kita, Frederic A. Rasio +1
The orbital eccentricity of a single planet around a component of a stellar binary system with a sufficiently large mutual inclination angle is known to oscillate on a secular time…
Two Jovian-Mass Planets in Earthlike Orbits
Sarah E. Robinson, Gregory Laughlin, Steven S. Vogt +7
We report the discovery of two new planets: a 1.94 M_Jup planet in a 1.8-year orbit of HD 5319, and a 2.51 M_Jup planet in a 1.1-year orbit of HD 75898. The measured eccentricities…
