GPS & CSS radio sources and space-VLBI
I. A. G. Snellen
A short overview is given of the status of research on young extragalactic radio sources. We concentrate on Very Long Baseline Interferometric (VLBI), and space-VLBI results obtain…
Precise radial velocities of giant stars. IV. A correlation between surface gravity and radial velocity variation and a statistical investigation of companion properties
S. Hekker, I. A. G. Snellen, C. Aerts +3
Since 1999, we have been conducting a radial velocity survey of 179 K giants using the CAT at UCO/Lick observatory. At present ~20-100 measurements have been collected per star wit…
A sample of mJy radio sources at 1.4 GHz in the Lynx and Hercules fields - II. Cosmic evolution of the space density of FRI radio sources
E. E. Rigby, P. N. Best, I. A. G. Snellen
In this paper the cosmic evolution of the space density of Fanaroff & Riley Class I (FRI) radio sources is investigated out to z ~ 1, in order to understand the origin of the diffe…
A search for transiting extrasolar planet candidates in the OGLE-II microlens database of the galactic plane
I. Snellen, R. van der Burg, M. de Hoon +1
In the late 1990s, the Optical Gravitational Lensing Experiment (OGLE) team conducted the second phase of their long-term monitoring programme, OGLE-II, which since has been supers…
Radial velocities of giant stars: an investigation of line profile variations
S. Hekker, I. A. G. Snellen, C. Aerts +3
Since 1999, a radial velocity survey of 179 red giant stars is ongoing at Lick Observatory with a one month cadence. At present ~20-100 measurements have been collected per star wi…
The spin axes orbital alignment of both stars within the eclipsing binary system V1143Cyg using the Rossiter-McLaughlin effect
S. Albrecht, S. Reffert, I. Snellen +2
Context: The Rossiter-McLaughlin (RM) effect, a rotational effect in eclipsing systems, provides unique insight into the relative orientation of stellar spin axes and orbital axes…
