The Jupiter Twin HD 154345b
J. T. Wright, G. W. Marcy, R. P. Butler +4
We announce the discovery of a twin of Jupiter orbiting the slightly metal-poor ([Fe/H] = -0.1) nearby (d = 18 pc) G8 dwarf HD 154345. This planet has a minimum mass of 0.95 Jupite…
Five Planets Orbiting 55 Cancri
Debra A. Fischer, Geoffrey W. Marcy, R. Paul Butler +9
We report 18 years of Doppler shift measurements of a nearby star, 55 Cancri, that exhibit strong evidence for five orbiting planets. The four previously reported planets are stron…
On the Search For Transits of the Planets Orbiting Gl 876
P. D. Shankland, E. J. Rivera, G. Laughlin +14
We report the results of a globally coordinated photometric campaign to search for transits by the P ~ 30 d and P ~ 60 d outer planets of the 3-planet system orbiting the nearby M-…
Measurement of the Spin-Orbit Alignment in the Exoplanetary System HD 189733
Joshua N. Winn, John A. Johnson, Geoffrey W. Marcy +9
We present spectroscopy of a transit of the exoplanet HD 189733b. By modeling the Rossiter-McLaughlin effect (the anomalous Doppler shift due to the partial eclipse of the rotating…
A ~ 7.5 Earth-Mass Planet Orbiting the Nearby Star, GJ 876
E. J. Rivera, J. J. Lissauer, R. P. Butler +6
High precision, high cadence radial velocity monitoring over the past 8 years at the W. M. Keck Observatory reveals evidence for a third planet orbiting the nearby (4.69 pc) dM4 st…
The N2K Consortium. II. A Transiting Hot Saturn Around HD 149026 With a Large Dense Core
B. Sato, D. A. Fischer, G. W. Henry +18
Doppler measurements from Subaru and Keck have revealed radial velocity variations in the V=8.15, G0IV star HD 149026 consistent with a Saturn-Mass planet in a 2.8766 day orbit. Ph…
