| Abstract: |
Interferometric imaging in the near-infrared allows us to probe the
circumstellar environments of nearby bright stars with milli-arc-seconds
resolution. In this paper, we present the first synthesized spectral line
(Brγ) image of the Be star ω(28) CMa, obtained with the
AMBER/VLTI high resolution data. Images were synthesized in 100 spectral
channels covering the Brγ line using the squared visibilities and the
closure phases. These images were further refined using the self-calibration
procedure proposed by Millour et al. (2011). We present both the
continuum image and the image obtained within the Brγ line. |
