The angular sizes of dwarf stars and subgiants Surface brightness relations calibrated by interferometry
The availability of a number of new interferometric measurements of Main Sequence and subgiant stars makes it possible to calibrate the surface brightness relations of these stars using exclusivelyExpand

VLTI near-IR interferometric observations of Vega-like stars: Radius and age of a PsA, b Leo, b Pic, e Eri and t Cet
We report in this paper the direct interferometric measurement of the angular diameter of five nearby Vega-like stars: α PsA, β Leo, β Pic, � Eri and τ Cet. The near-infrared (K and H bands)Expand

Mass-radius relation of low and very low-mass stars revisited with the VLTI
We measured the radii of 7 low and very low-mass stars using long baseline interferometry with the VLTI interferometer and its VINCI and AMBER near-infrared recombiners. We use these new data,Expand

Circumstellar material in the Vega inner system revealed by CHARA/FLUOR
Context. Only a handful of debris disks have been imaged up to now. Due to the need for high dynamic range and high angular resolution, very little is known about the inner planetary region, whereExpand

The spinning-top Be star Achernar from VLTI-VINCI
We report here the first observations of a rapidly rotating Be star, Eridani, using Earth-rotation synthesis on the Very Large Telescope (VLT) Interferometer. Our measures correspond to a 2a=2b= 1:56Expand

TW Hydrae: evidence of stellar spots instead of a Hot Jupiter
Context. TW Hya is a classical T Tauri star that shows significant radial-velocity variations in the optical regime. These variations have been attributed to a 10 MJup planet orbiting the star atExpand

New insights on the AU-scale circumstellar structure of FU Orionis
We report new near-infrared, long-baseline interferometric observations at the AU scale of the pre-main-sequence star FU Orionis with the PTI, IOTA and VLTI interferometers. This young stellar objectExpand

A sensitive survey for 13CO, CN, H2CO, and SO in the disks of T Tauri and Herbig Ae stars
Aims. We investigate the suitability of several molecular tracers, in particular CN N = 2−1 line emission, as a confusion-free probe of the kinematics of circumstellar disks. Methods. We use the IRAMExpand

A near-infrared interferometric survey of debris disk stars. I. Probing the hot dust content aroun
Context. The quest for hot dust in the central region of debris disks re quires high resolution and high dynamic range imaging. Nearinfrared interferometry is a powerful means to directly det ectExpand
