Tests of achromatic phase shifters performed on the SYNAPSE test bench: a progress report
Pavel Gabor, Peter A. Schuller, Bruno Chazelas +16
The achromatic phase shifter (APS) is a component of the Bracewell nulling interferometer studied in preparation for future space missions (viz. Darwin/TPF-I) focusing on spectrosc…
The limb-darkened Arcturus; Imaging with the IOTA/IONIC interferometer
S. Lacour, S. Meimon, E. Thiebaut +14
This paper is an H band interferometric examination of Arcturus, a star frequently used as a spatial and spectral calibrator. Using the IOTA 3 telescope interferometer, we performe…
Stabilising a nulling interferometer using optical path difference dithering
Pavel Gabor, Bruno Chazelas, Frank Brachet +5
Context. Nulling interferometry has been suggested as the underlying principle for the Darwin and TPF-I exoplanet research missions. Aims. There are constraints both on the mean va…
No Expanding Fireball: Resolving the Recurrent Nova RS Ophiuchi with Infrared Interferometry
J. D. Monnier, R. K. Barry, W. A. Traub +17
Following the recent outburst of the recurrent nova RS Oph on 2006 Feb 12, we measured its near-infrared size using the IOTA, Keck, and PTI Interferometers at multiple epochs. The…
Study of molecular layers in the atmosphere of the supergiant star mu Cep by interferometry in the K band
G. Perrin, S. T. Ridgway, T. Verhoelst +5
Infrared interferometry of supergiant and Mira stars has recently been reinterpreted as revealing the presence of deep molecular layers. Empirical models for a photosphere surround…
Is Arcturus a well-understood K giant? Test of model atmospheres and potential companion detection by near-infrared interferometry
T. Verhoelst, P. J. Bordé, G. Perrin +8
We present near-IR interferometric measurements of the K1.5 giant Arcturus (alpha Bootis), obtained at the IOTA interferometer with the FLUOR instrument, in four narrow filters wit…
Direct Detection of Sub-stellar Companions with MIDI
Peter Schuller, Martin Vannier, Romain Petrov +4
Current detection methods of planetary companions do not allow retrieving their spectral information properties. The method of Differential Interferometry has the potential to comp…
LLiST - a new star tracker camera for tip-tilt correction at IOTA
P. A. Schuller, M. G. Lacasse, D. Lydon +5
The tip-tilt correction system at the Infrared Optical Telescope Array (IOTA) has been upgraded with a new star tracker camera. The camera features a backside-illuminated CCD chip…
Are dust shell models well-suited to explain interferometric data of late-type stars in the near-infrared?
P. Schuller, P. Salomé, G. Perrin +7
Recently available near-infrared interferometric data on late-type stars show a strong increase of diameter for asymptotic giant branch (AGB) stars between the K (2.0 - 2.4 μm) and…
