Four new `hot Jupiter` extrasolar planets have been detected as part of the Hungarian-made Automated Telescope Network-South (HATSouth) exoplanet survey. The newly found alien worlds are generally similar in size, but vary widely in mass. The discovery is detailed in a paper published April 4 on the arXiv pre-print server.
