First AMBER/VLTI Observations of Hot Massive Stars
AMBER is the first near infrared focal instrument of the VLTI. It combines three telescopes and produces spectrally resolved interferometric measures. This paper discusses some preliminary results of the first scientific observations of AMBER with three Unit Telescopes at medium (1500) and high (12000) spectral resolution. We derive a first set of constraints on the […]
Disentangling the Wind and the Disk in the Close Surrounding of the Young Stellar Object MWC297 with AMBER/VLTI
The young stellar object MWC297 is a B1.5Ve star exhibiting strong hydrogen emission lines. This object has been observed by the AMBER/VLTI instrument in 2-telescope mode in a sub-region of the K spectral band centered around the Brγ line at 2.1656μm. The object has not only been resolved in the continuum with a visibility of […]
VEGA: A Visible Spectrograph and Polarimeter for the VLTI
The ESO/VLTI has now clearly a position of world leader in the domain of ground-based optical interferometry. With four 8.2 m telescopes and two (four) 1.8 m telescopes, the Paranal Observatory is without any doubt the best optical interferometric facility in the world. Since many years, it has attracted the major part of the European […]
