A detailed analysis of the HD 73526 2:1 resonant planetary system
(2014-01-10)
We present six years of new radial velocity data from the Anglo-Australian and Magellan Telescopes on the HD 73526 2:1 resonant planetary system. We investigate both Keplerian and dynamical ( interacting) fits to these ...

(2013-09)
Determining the orbital eccentricity of an extrasolar planet is critically important for understanding the system's dynamical environment and history. However, eccentricity is often poorly determined or entirely mischaracterized ...
The Anglo-Australian planet search. XXII : Two new multi-planet systems
(2012-07-10)
We report the detection of two new planets from the Anglo-Australian Planet Search. These planets orbit two stars each previously known to host one planet. The new planet orbiting HD 142 has a period of 6005 +/- 427 days, ...
