The ESPRI project: astrometric exoplanet search with PRIMA I. Instrument description and performance of first light observations
J. Sahlmann, T. Henning, D. Queloz +42
The ESPRI project relies on the astrometric capabilities offered by the PRIMA facility of the Very Large Telescope Interferometer for the discovery and study of planetary systems.…
Fringe tracking performance monitoring: FINITO at VLTI
A. Merand, F. Patru, J. -P. Berger +2
Since April 2011, realtime fringe tracking data are recorded simultaneously with data from the VLTI/AMBER interferometric beam combiner. Not only this offers possibilities to post-…
Narrow-angle astrometry with PRIMA
J. Sahlmann, D. Ségransan, A. Mérand +16
The Extrasolar Planet Search with PRIMA project (ESPRI) aims at characterising and detecting extrasolar planets by measuring the host star's reflex motion using the narrow-angle as…
Mean angular diameters, distances and pulsation modes of the classical Cepheids FF Aql and T Vul - CHARA/FLUOR near-infrared interferometric observations
A. Gallenne, P. Kervella, A. Mérand +8
We report the first angular diameter measurements of two classical Cepheids, FF Aql and T Vul, that we have obtained with the FLUOR instrument installed at the CHARA interferometri…
Interferometry, spectroscopy and astrometry of the bright eclipsing system Delta Velorum
P. Kervella, A. Mérand, T. Pribulla
The bright southern star Delta Vel is a multiple system comprising at least three stars. Its brightest component, Delta Vel A, was identified in 2000 as one of the brightest eclips…
The long-period Galactic Cepheid RS Puppis - II. 3D structure and mass of the nebula from VLT/FORS polarimetry
P. Kervella, A. Mérand, L. Szabados +7
The long-period Cepheid RS Pup is surrounded by a large dusty nebula reflecting the light from the central star. Due to the changing luminosity of the central source, light echoes…
