H. Jones (U. Hertfordshire, UK), Anglo-Australian Planet Search Team
The Anglo-Australian Planet Search is a long-term programme being carried out on the Anglo-Australian Telescope to search for giant planets around nearby Solar type stars. We began observing in January 1998 observing 200 target stars over 20 nights per year, and have very recently grown to more than 60 nights per year targetting an expanded sample. Twenty planet candidates with M sin i values ranging from 0.2 to 10 Mjup have been found from the programme, four planet candidates have been confirmed using our data and several found by other programmes disputed. Our precision Doppler velocity measurements are made with the an echelle spectrograph with an iodine absorption cell. The iodine cell enables us to achieve measured long-term velocity stability of 2 m/s (for suitably stable stars) down to our survey magnitude limit. This stability will be discussed in the context of our latest results which include the discovery of two highly elliptical planets.
We acknowledge support for this programme by the partners of the Anglo-Australian Telescope agreement as well as from NSF and NASA.
