A planetary system with gas giants and super-Earths around the nearby M dwarf GJ676A : Optimizing data analysis techniques for the detection of multi-planetary systems
(2012-12-01)
Context. Several M dwarfs are targets of systematical monitoring in searches for Doppler signals caused by low-mass exoplanet companions. As a result, an emerging population of high-multiplicity planetary systems around ...
Evidence for nine planets in the HD 10180 system
(2012-07-01)
Aims. We re-analyse the HARPS radial velocities of HD 10180 and calculate the probabilities of models with differing numbers of periodic signals in the data. We test the significance of the seven signals, corresponding to ...
Bayesian analysis of the radial velocities of HD 11506 reveals another planetary companion
(2009-03-01)
Aims. We aim to demonstrate the efficiency of a Bayesian approach in analysing radial velocity data by reanalysing a set of radial velocity measurements. Methods. We present Bayesian analysis of a recently published set ...
The complementarity of astrometrie and radial velocity exoplanet observations: : Determining exoplanet mass with astrometric snapshots
(2009-02)
Aims. It is commonly assumed that the two indirect exoplanet detection methods, the radial velocity method and astrometric method, require observational periods exceeding the orbital period to produce positive results. ...
