New Planets around Three G Dwarfs
Simon J. O'Toole, R. Paul Butler, C. G. Tinney +8
Doppler velocity measurements from the Anglo-Australian Planet Search reveal planetary mass companions to HD23127, HD159868, and a possible second planetary companion to HD154857.…
Four New Exoplanets and Hints of Additional Substellar Companions to Exoplanet Host Stars
J. T. Wright, G. W. Marcy, D. A. Fischer +8
We present four new exoplanets: HIP 14810 b & c, HD 154345 b, and HD 187123 c. The two planets orbiting HIP 14810, from the N2K project, have masses of 3.9 and 0.76 M_jup. We have…
On the Double Planet System Around HD 83443
R. Paul Butler, Geoffrey W. Marcy, Steven S. Vogt +6
The Geneva group has reported two Saturn-mass planets orbiting HD 83443 (K0V) with periods of 2.98 and 29.8 d. The two planets have raised interest in their dynamics because of the…
Ten Low Mass Companions from the Keck Precision Velocity Survey
Steven S. Vogt, R. Paul Butler, Geoffrey W. Marcy +4
Ten new low mass companions have emerged from the Keck precision Doppler velocity survey, with minimum (msini) masses ranging from 0.8 mjup to 0.34 msun. Five of these are planet c…
First Results from the Anglo-Australian Planet Search - A Brown Dwarf Candidate and a 51 Peg-like Planet
C. G. Tinney, R. Paul Butler, Geoffrey W. Marcy +5
We report results from the Anglo-Australian Planet Search -- a survey for planets around 200 solar-type stars in the southern hemisphere, which is being carried out on the 3.9m Ang…
Six New Planets from the Keck Precision Velocity Survey
Steven S. Vogt, Geoffrey W. Marcy, R. Paul Butler +1
We report results of a search for planets around 500 main sequence stars using the Keck high resolution spectrometer which has provided Doppler precision of 3 m/s during the past 3…
