TWO EXTRASOLAR PLANETS FROM THE ANGLO-AUSTRALIAN PLANET SEARCH

摘要

We report the detection of two new extrasolar planets from the Anglo-Australian Planet Search around the stars HD 142 and HD 23079. The planet orbiting HD 142 has an orbital period of just under 1 yr, while that orbiting HD 23079 has a period of just under 2 yr. HD 142 falls into the class of " eccentric " gas giants. HD 23079 joins the group of "∈ Ret-like" gas giant planets, with near-circular orbits outside a radius of 0.1 AU. The recent discovery of several more members of this class provides new impetus for the extension of existing planet searches to longer periods in the search for Jupiter-like planets in Jupiter-like orbits.
