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…
