Measurements of Balmer emission line profiles for southern Be stars. II. New data and radial velocities.

The results of an analyses of more than 500 H alpha, H beta and H gamma line profiles from 55 bright Be and mostly early type Be shell-type stars over the period 1980-83 are reported. The photoelectrically-determined spectra were reduced for equivalent widths and half-widths at different epochs, 200 Balmer line profiles and variations, and radial velocities. The data supported a rotating disk model and a functional relationship between the equivalent width and the envelope diameter. Electron scattering at H alpha may have produced H alpha emission line half widths which were predominantly larger than H beta lines. Persistent asymmetries of particular Balmer emission lines and positive Balmer progressions of the radial velocity were taken to indicate a phase of continuous inflow through the envelope. Details of the observed emissions of each star are discussed.
