Abstract
The AMBER instrument installed at the Very Large Telescope (VLT)
combines three beams from as many telescopes to produce spectrally
dispersed fringes from milli-arcsecond angular scale in the near
infrared. Two years after installation, first scientific observations
have been carried out during the Science Demonstration Time and the
Guaranteed Time mostly on bright sources due to some VLTI limitations.
In this paper, we review these first astrophysical results and we show
which types of completely new information is brought by AMBER. The
first astrophysical results have been mainly focusing on stellar wind
structure, kinematics, and its interaction with dust usually
concentrated in a disk. Because AMBER has dramatically increased the
number of measures per baseline, this instrument brings strong
constraints on morphology and models despite a relatively poor (u,v)
coverage for each object.
