The angular sizes of dwarf stars and subgiants Surface brightness relations calibrated by interferometry
- P. Kervella, F. Th'evenin, E. D. Folco, D. S'egransan
- Physics
- 8 April 2004
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 exclusively… Expand
VLTI near-IR interferometric observations of Vega-like stars: Radius and age of a PsA, b Leo, b Pic, e Eri and t Cet
- E. D. Folco, F. Th'evenin, +4 authors P. Morel
- Physics
- 1 November 2004
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
- B.-O. Demory, D. S'egransan, +7 authors C. Perrier
- Physics
- 2 June 2009
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
- O. Absil, E. D. Folco, +11 authors H. Mcalister
- Physics
- 12 April 2006
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, where… Expand
The spinning-top Be star Achernar from VLTI-VINCI
- A. D. D. Souza, P. Kervella, +4 authors F. Paresce
- Physics
- 13 June 2003
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= 1:56… Expand
TW Hydrae: evidence of stellar spots instead of a Hot Jupiter
- N. Huélamo, P. Figueira, +12 authors S. Udry
- Physics
- 18 August 2008
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 at… Expand
New insights on the AU-scale circumstellar structure of FU Orionis
- F. Malbet, R. Lachaume, +7 authors W. Traub
- Physics
- 29 March 2005
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 object… Expand
AN INTERFEROMETRIC STUDY OF THE FOMALHAUT INNER DEBRIS DISK. I. NEAR-INFRARED DETECTION OF HOT DUST WITH VLTI/VINCI*
- O. Absil, B. Mennesson, Jean-Baptiste Le Bouquin, E. D. Folco, P. Kervella, J. Augereau
- Physics
- 21 August 2009
The innermost parts of dusty debris disks around main sequence stars are currently poorly known due to the high contrast and small angular separation with their parent stars. Using near-infrared… Expand
A sensitive survey for 13CO, CN, H2CO, and SO in the disks of T Tauri and Herbig Ae stars
- S. Guilloteau, E. D. Folco, +12 authors France
- Physics
- 20 November 2012
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 IRAM… Expand
A near-infrared interferometric survey of debris disk stars. I. Probing the hot dust content aroun
- E. D. Folco, O. Absil, +16 authors Institut d'Astrophysique et de G'eophysique Universit'e de Observatory
- Physics
- 9 October 2007
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 ect… Expand
