Hot Jupiters in the Southern Sky: The HAT-South Project
HAT-South is a project to search for transiting extrasolar planets in
the Southern Hemisphere. It will use a network of wide-field
telescopes to monitor hundreds of thousands of bright stars, searching
for the characteristic dip in light that occurs when a planet passes
in front of its host star. With follow-up observations, the planets
discovered in this project will be studied extensively to determine
their density, temperature, and even atmospheric composition.
The HAT-South telescopes will be located in three sites around the
Southern Hemisphere: at Siding Spring Observatory (Australia), Las
Campanas Observatory (Chile), and the Hess Site (Namibia). These
locations will allow fields to be monitored 24 hours per day, which
will greatly increase the rate at which planets can be discovered.
Each site will host two "TH4" units. These TH4 units consist of four
0.18m Takahashi astrographs fitted with Apogee 4Kx4K CCDs. Each TH4
unit monitors 64 square degrees of sky at a time, so each site will be
capable of monitoring 128 square degrees of sky.
The HAT-South project is a collaboration between the Australia National
University (ANU), the Harvard/Smithsonian Center for Astrophysics
(CfA), and the Max Planck Institute for Astronomy (MPIA). For further

Update on Siding Spring Installation
The ANU is currently undertaking work to prepare for the installation of the two TH4 units at Siding Spring Observatory, Australia. The progress to date
is set out below.
