The close circumstellar environment of the semi-regular S-type star Pi^1 Gruis
Stéphane Sacuto, Alain Jorissen, Pierre Cruzalèbes +4
We study the close circumstellar environment of the nearby S-type star Pi^1 Gruis using high spatial-resolution, mid-infrared observations from the ESO/VLTI. Spectra and visibiliti…
A compact dust shell in the symbiotic system HM Sge
Stéphane Sacuto, Olivier Chesneau, Martin Vannier +1
We present high spatial resolution observations of the mid-infrared core of the dusty symbiotic system HM Sge. The MIDI interferometer was used with the VLT UTs and ATs providing b…
SearchCal: a Virtual Observatory tool for searching calibrators in optical long baseline interferometry. I: The bright object case
Daniel Bonneau, J. -M. Clausse, X. Delfosse +6
In long baseline interferometry, the raw fringe contrast must be calibrated to obtain the true visibility and then those observables that can be interpreted in terms of astrophysic…
The last gasps of VY CMa: Aperture synthesis and adaptive optics imagery
J. D. Monnier, P. G. Tuthill, B. Lopez +3
We present new observations of the red supergiant VY CMa at 1.25 micron, 1.65 micron, 2.26 micron, 3.08 micron and 4.8 micron. Two complementary observational techniques were utili…
