Kinematic Be disk

Description

Model of the geometry (size and shape) and kinematics (rotation and expansion) of circumstellar disks, especially of Be stars. It is suited to interpret spectro-interferometric data (combination of high angular and high spectral resolutions) obtained on emission lines formed in the disk. The disk is assumed to be geometrically flat and its rotation and expansion velocities are defined by parameterized analytical laws. The intensity contribution from the continuum and line emissions are also given by parameterized laws. The units of the intensity maps are such that summing over all pixels (wavelength by wavelength) results in a spectral flux profile normalized to 1 in the continuum.
