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. ...
A wide deep infrared look at the Pleiades with UKIDSS : New constraints on the substellar binary fraction and the low-mass initial mass function
(2007-09-01)
We present the results of a deep wide-field near-infrared survey of 12 deg2 of the Pleiades conducted as part of the United Kingdom Infrared Telescope (UKIRT) Infrared Deep Sky Survey (UKIDSS) Galactic Cluster Survey (GCS). ...
Air mass modification over the Europe : EARLINET aerosol observations from Wales to Belarus
(2004-12-27)
For the first time, the vertically resolved aerosol optical properties of western and central/eastern European haze are investigated as a function of air mass transport. Special emphasis is put on clean maritime air masses ...
