The Absolute Magnitudes of Wolf-Rayet Stars HD 151932 and HD 152270

Shylaja, B. S; Bappu, M. K. V (Indian Institute of Astrophysics, Bangalore, 1983)

The absolute visual magnitudes of two Wolf-Rayet stars HD 151932 (WN 7) and HD 152270 (WC 7+08) have been determined from their energy distributions and monochromatic magnitudes least contaminated by emission lines taking ...
The He II 5411 Å velocity curve of the Wolf-Rayet eclipsing system HD 214419

Giridhar, S (Indian Institute of Astrophysics, 1978)

A velocity curve of the Wolf-Rayet eclipsing system HD 214419 is obtained from measures on prismatic spectra of the Hell 5411 emission line. The shape of the velocity curve is unlike that obtained for Hell 4686. The emission ...
Violet absorption edges of C IV lines in Wolf-Rayet spectra: possible superposition with diffuse interstellar bands at 5780 Å and 5797 Å

Giridhar, S; Bappu, M. K. V (Indian Institute of Astrophysics, 1978)

It is shown that the violet edges normally seen in Wolf-Rayet stars around 5800Å are principally due to displaced C IV absorption. The diffuse interstellar bands are seldom of comparable strength and can be seen separately ...
