Precise radial velocities of giant stars VIII. Testing for the presence of planets with CRIRES Infrared Radial Velocities

Trifon Trifonov, Sabine Reffert, Mathias Zechmeister +2

We have been monitoring 373 very bright (V < 6 mag) G and K giants with high precision optical Doppler spectroscopy for more than a decade at Lick Observatory. Our goal was to disc…

Disentangling 2:1 resonant radial velocity orbits from eccentric ones and a case study for HD 27894

Martin Kürster, Trifon Trifonov, Sabine Reffert +2

In radial velocity observations, a pair of extrasolar planets near a 2:1 orbital resonance can be misinterpreted as a single eccentric planet, if data are sparse and measurement pr…
