  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.
