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. Folco, F. Thévenin, +5 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

High-resolution imaging of dust shells by using Keck aperture masking and the IOTA interferometer

J. Monnier, R. Millan-Gabet, +12 authors A. U. Berkeley
Physics
19 January 2004

We present first results of an experiment to combine data from Keck aperture masking and the Infrared-Optical Telescope Array to image the circumstellar environments of evolved stars with ~20 mas… Expand

BINARY STARS IN THE ORION TRAPEZIUM CLUSTER CORE

M. Petr, V. C. Foresto, S. Beckwith, A. Richichi, M. Mccaughrean
Physics
20 June 1998

We have obtained high angular resolution (013 FWHM) near-infrared images of the central ~40'' × 40'' of the Trapezium cluster, using a speckle holography technique that we describe in detail. A… Expand

A geometric distance measurement to the Galactic Center black hole with 0.3% uncertainty

R. Abuter, A. Amorim, +51 authors S. Yazici
Physics
11 April 2019

We present a 0.16% precise and 0.27% accurate determination of R0, the distance to the Galactic Center. Our measurement uses the star S2 on its 16-year orbit around the massive black hole Sgr A* that… Expand

Cepheid distances from infrared long-baseline interferometry III. Calibration of the surface brightness-color relations

P. Kervella, D. Bersier, D. Mourard, N. Nardetto, P. Fouqué, V. C. Foresto
Physics
1 December 2004

The recent VINCI/VLTI observations presented in Paper I have nearly doubled the total number of available angular diameter measurements of Cepheids. Taking advantage of the significantly larger color… Expand

First Results from the CHARA Array. VII. Long-Baseline Interferometric Measurements of Vega Consistent with a Pole-On, Rapidly Rotating Star

J. Aufdenberg, A. Mérand, +10 authors N. Turner
Physics
13 March 2006

We have obtained high-precision interferometric measurements of Vega with the CHARA Array and FLUOR beam combiner in the K’ band at projected baselines between 103m and 273m. The measured visibility… Expand

Interferometric observations of the supergiant stars α Orionis and α Herculis with FLUOR at IOTA

G. Perrin, S. Ridgway, V. C. Foresto, B. Mennesson, W. Traub, M. Lacasse
Physics
4 February 2004

We report the observations in the K band of the red supergiant star α Orionis and of the bright giant star α Herculis with the FLUOR beamcombiner at the IOTA interferometer. The high quality of the… Expand

Circumstellar material in the Vega inner system revealed by CHARA/FLUOR

O. Absil, E. 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

Unveiling Mira stars behind the molecules - Confirmation of the molecular layer model with narrow band near-infrared interferometry

G. Perrin, S. Ridgway, +8 authors M. Lacasse
Physics
1 October 2004

We have observed Mira stars with the FLUOR beamcombiner on the IOTA interferometer in narrow bands around $2.2\,\mu$m wavelength. We find systematically larger diameters in bands contaminated by… Expand

A catalog of bright calibrator stars for 200-m baseline near-infrared stellar interferometry

A. Mérand, P. Bordé, V. C. Foresto
Physics
10 December 2004

We present in this paper a catalog of reference stars suitable for calibrating infrared interferometric observations. In the K band, visibilities can be calibrated with a precision of 1% on baselines… Expand
