Selection functions in doppler planet searches
(2009)
We present a preliminary analysis of the sensitivity of Anglo-Australian Planet Search data to the orbital parameters of extrasolar planets. To do so, we have developed new tools for the automatic analysis of large-scale ...
A Neptune-mass Planet Orbiting the Nearby G Dwarf HD 16417
(2009)
Precision Doppler measurements from an intensive 48 night "Rocky Planet Search" observing campaign on the Anglo-Australian Telescope (AAT) have revealed the presence of a low-mass exoplanet orbiting the G1 dwarf HD 16417. ...
The frequency of low-mass exoplanets
(2009)
We report first results from the Anglo-Australian Telescope Rocky Planet Search—an intensive, high-precision Doppler planet search targeting low-mass exoplanets in contiguous 48 night observing blocks. On this run, we ...
Beyond the Iron Peak: r- and s-process Elemental Abundances in Stars with Planets
(2008)
We present elemental abundances of 118 stars (28 of which are known extrasolar planetary host stars) observed as part of the Anglo-Australian Planet Search. Abundances of O, Mg, Cr, Y, Zr, Ba, Nd, and Eu (along with ...
High-eccentricity planets from the Anglo-Australian planet search
(2006)
We report Doppler measurements of the stars HD 187085 and HD 20782 which indi- cate two high eccentricity low-mass companions to the stars. We find HD 187085 has a Jupiter-mass companion with a 1000 d orbit. Our formal ...
The 2:1 resonant exoplanetary system orbiting HD 73526
(2006)
We report the detection of a second exoplanet orbiting the G6 V dwarf HD 73526. This second planet has an orbital period of 377 days, putting it in a 2:1 resonance with the previously known exoplanet, the orbital period ...
