Precise Doppler measurements from the Anglo-Australian Telescope (AAT) UCLES spectrometer reveal periodic Keplerian velocity variations in the stars HD 160691 and HD 27442. HD 160691 has a period of 743 days, a semiamplitude of 54 m s~1, and a high eccentricity, e \ 0.62, typical of extrasolar planets orbiting beyond 0.2 AU. The minimum (M sin i) mass of the companion is 1.97 and the M J , semimajor axis is 1.65 AU. HD 27442 has a 415 day period, a semiamplitude of 32 m s~1, and an eccentricity… Expand
Extrasolar planets around HD 196050, HD 216437 and HD 160691
We report precise Doppler measurements of the stars HD 216437, HD 196050 and HD 160691 obtained with the Anglo-Australian Telescope using the UCLES spectrometer together with an iodine cell as partExpand
Three low-mass planets from the Anglo-Australian planet search
We report the detection of three new low-mass planets from the Anglo-Australian Planet Search. The three parent stars of these planets are chromospherically quiet main-sequence G dwarfs withExpand
On the Double-Planet System around HD 83443
The Geneva group has reported two Saturn-mass planets orbiting HD 83443 (K0 V) with periods of 2.98 and 29.8 days. The two planets have raised interest in their dynamics because of the possible 10 :Expand
High-eccentricity planets from the Anglo-Australian Planet Search
We report Doppler measurements of the stars HD 187085 and HD 20782 which indicate two high eccentricity low-mass companions to the stars. We find HD 187085 has a Jupiter-mass companion with a �1000 dExpand
Multiple Companions to HD 154857 and HD 160691
Precise Doppler measurements from the Anglo-Australian Telescope (AAT) UCLES spectrometer reveal two companions to both HD 154857 and HD 160691. The inner companion to HD 154857 has a period of 398Expand
Four New Planets Orbiting Metal-enriched Stars*
We report the detection of four new extrasolar planets from the Anglo-Australian Planet Search orbiting the metal-enriched stars HD 73526, HD 76700, HD 30177, and HD 2039. The planetary companion ofExpand
The Anglo-Australian planet search. XX. A solitary ice-giant planet orbiting HD 102365
We present 12 years of precision Doppler data for the very nearby G3 star HD?102365, which reveals the presence of a Neptune-like planet with a 16.0 M Earth minimum mass in a 122.1 day orbit. VeryExpand
A JUPITER-LIKE PLANET ORBITING THE NEARBY M DWARF GJ 832*
Precision Doppler velocity measurements from the Anglo-Australian Telescope reveal a planet with a 9.4 ± 0.4 year period orbiting the M1.5 dwarf GJ 832. Within measurement uncertainty the orbit isExpand
The Pan-Pacific Planet Search. II. Confirmation of a Two-planet System around HD 121056
Precise radial velocities from the Anglo-Australian Telescope (AAT) confirm the presence of a rare short-period planet around the K0 giant HD 121056. An independent two-planet solution using the AATExpand
The Anglo-Australian planet search. XXI. A gas-giant planet in a one year orbit and the habitability of gas-giant satellites
We have detected the Doppler signature of a gas-giant exoplanet orbiting the star HD 38283, in an eccentric orbit with a period of almost exactly one year (P = 363.2 ± 1.6 d, m sin i = 0.34 ± 0.02 MExpand
