Ultraviolet Si IV/C IV ratios for Be stars
Description
The intensities of the very strong lines of C IV lambda 1549 A and Si IV lambdalambda 1394, 1403 A observed in spectra obtained with Skylab experiment S019 provide a sensitive discrimination of spectral type between B0 and B2. Eye estimates of the Si IV/C IV ratio are tabulated for 33 B0-B2, class III-V stars of which 11 are emission-line stars. Seven of the emission-line stars show significantly smaller ratios than normal stars of the same MK class. (Auth.)
