VLTI monitoring of the dust formation event of the Nova V1280 Sco
Olivier Chesneau, Dipankar Banerjee, F. Millour +13
We present the first high spatial resolution monitoring of the dust forming nova V1280 Sco performed with the Very Large Telescope Interferometer (VLTI). Spectra and visibilities w…
High angular resolution N-band observation of the silicate carbon star IRAS08002-3803 with the VLTI/MIDI instrument
Keiichi Ohnaka, T. Driebe, K. -H. Hofmann +10
We present the results of N-band spectro-interferometric observations of the silicate carbon star IRAS08002-3803 with the MID-infrared Interferometric instrument (MIDI) at the Very…
First VLTI/MIDI observations of a Be star: Alpha Ara
Olivier Chesneau, A. Meilland, T. Rivinius +12
We present the first VLTI/MIDI observations of the Be star Alpha Ara, showing a nearly unresolved circumstellar disk in the N band. The interferometric measurements made use of the…
The sub-arcsecond dusty environment of Eta Carinae
O. Chesneau, M. Min, T. Herbst +15
The core of the nebula surrounding Eta Carinae has been observed with the VLT Adaptive Optics system NACO and with the interferometer VLTI/MIDI to constrain spatially and spectrall…
Calibration Observations of Fomalhaut with the VLTI
J. Davis, A. Richichi, P. Ballester +6
An investigation of the stability of the transfer function of the European Southern Observatory's Very Large Telescope Interferometer has been carried out through observations of F…
High-resolution imaging of dust shells using Keck aperture masking and the IOTA Interferometer
J. D. Monnier, R. Millan-Gabet, P. G. Tuthill +10
We present first results of an experiment to combine data from Keck aperture masking and the Infrared-Optical Telescope Array (IOTA) to image the circumstellar environments of evol…
