| Abstract: |
We are investigating the circumstellar material for a sample of B[e] stars
using high spectral resolution data taken in the optical and near-infrared
regions with ESO/FEROS and ESO/CRIRES spectrographs, respectively. B[e] stars
are surrounded by dense disks of still unknown origin. While optical emission
lines from [O I] and [Ca II] reflect the disk conditions close
to the star (few stellar radii), the near-infrared data, especially the CO
band emission, mirror the characteristics in the molecular part of the disk
farther away from the star (several AU). Based on our high resolution
spectroscopic data, we seek to derive the density and temperature structure of
the disks, as well as their kinematics. This will allow us to obtain a better
understanding of their structure, formation history and evolution. Here we
present our preliminary results. |
