Abstract

We present updated simulations of the detectability of Jupiter analogs by the 17-year Anglo-Australian Planet Search. The occurrence rate of Jupiter-like planets that have remained near their formation locations beyond the ice line is a critical datum necessary to constrain the details of planet formation. It is also vital in our quest to fully understand how common (or rare) planetary systems like our own are in the Galaxy. From a sample of 202 solar-type stars, and correcting for imperfect detectability on a star-by-star basis, we derive a frequency of 6.2 +2.8 −1.6%
for giant planets in orbits from 3-7 AU. When a consistent definition of 'Jupiter analog' is used, our results are in agreement with those from other legacy radial velocity surveys.
