Nulling interferometry: performance comparison between Antarctica and other ground-based sites
O. Absil, V. Coude du Foresto, M. Barillot +1
Detecting the presence of circumstellar dust around nearby solar-type main sequence stars is an important pre-requisite for the design of future life-finding space missions such as…
FADE, an instrument to measure the atmospheric coherence time
A. Tokovinin, A. Kellerer, V. Coude Du Foresto
After proposing a new method of deriving the atmospheric time constant from the speed of focus variations (Kellerer & Tokovinin 2007), we now implement it with the new instrument,…
Extended envelopes around Galactic Cepheids III. Y Oph and alpha Per from near-infrared interferometry with CHARA/FLUOR
A. Mérand, J. Audenberg, P. Kervella +3
Unbiased angular diameter measurements are required for accurate distances to Cepheids using the interferometric Baade Wesselink method (IBWM). The precision of this technique is c…
Interferometric observations of the multiple stellar system delta Velorum
A. Kellerer, M. G. Petr-Gotzens, P. Kervella +1
delta Velorum is a nearby (24pc) triple stellar system, containing a close, eclipsing binary (Aa, Ab) discovered in 2000. Multiple systems provide an opportunity to determine the s…
Circumstellar material in the Vega inner system revealed by CHARA/FLUOR
O. Absil, E. di Folco, A. Merand +11
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…
First Results from the CHARA Array VII: Long-Baseline Interferometric Measurements of Vega Consistent with a Pole-On, Rapidly Rotating Star
J. P. Aufdenberg, A. Merand, V. Coude du Foresto +10
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 m…
