Precise Radial Velocities of Giant Stars VII. Occurrence Rate of Giant Extrasolar Planets as a Function of Mass and Metallicity
Sabine Reffert, Christoph Bergmann, Andreas Quirrenbach +2
(abridged) We have obtained precise radial velocities for a sample of 373 G and K type giants at Lick Observatory regularly over more than 12 years. Planets have been identified ar…
Searching for Earth-mass planets around Centauri: precise radial velocities from contaminated spectra
Christoph Bergmann, Michael Endl, John B. Hearnshaw +2
This work is part of an ongoing project which aims to detect terrestrial planets in our neighbouring star system Centauri using the Doppler method. Owing to the small angular s…
The Mt John University Observatory Search For Earth-mass Planets In The Habitable Zone Of Alpha Centauri
M. Endl, C. Bergmann, J. Hearnshaw +6
The "holy grail" in planet hunting is the detection of an Earth-analog: a planet with similar mass as the Earth and an orbit inside the habitable zone. If we can find such an Earth…
