Abstract (from CDS):
Doppler measurements from the high-resolution CORALIE spectrometer of the stars HD 75289
and HD 130322
reveal 2 new extra-solar giant planets. They are the second and third planetary candidates discovered with CORALIE in less than 1 year, since its installation on the 1.2-m Euler Swiss telescope at LaSilla. The minimum mass of the planet around HD 75289
) is the lightest found to date for a solar-type star companion. The orbital period is 3.5 days and the orbit is circular. The second candidate, a Jupiter-mass planet, orbits HD 130322
in 10.72 days, on an almost circular trajectory. Due to their small orbital periods, both planets belong to the hot Jupiter family, increasing thus the already large number of known Jupiter sized planets with orbits much smaller than in the solar system.
