  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.
