Hot wind from gam2 Vel observed in the ultraviolet.

Feibelman, W. A.; Kondo, Y.; West, D. K.

The close binary system Gamma(2) Vel, consisting of a WC8 and an O9 I star, has been observed in the ultraviolet at various phases. Preliminary analysis of selected data shows that the temperature of the stellar wind from this binary increases outward. This suggests that an additional source of energy other than radiation pressure may exist for th…

Ultraviolet shell formation at V1016 Cygni.

Feibelman, W. A.

A recent 330 minute high-resolution International Ultraviolet Explorer (IUE) spectrogram of V1016 Cygni shows splitting of the 1550 A component of the C IV resonance doublet, suggesting that a nebular shell is in the process of formation. An expansion velocity of 15 km/s is indicated by the IUE data and corresponds to the low range encountered wit…

Ultraviolet spectra of the X-ray transient A 0538-66.

Raymond, J. C.

Ultraviolet spectra were obtained before and after the optical spectrum changed from absorption to emission lines. The continuum brightness dropped by a factor of 2. Spectra with bright continua show N V, Si IV, and C IV in absorption, while the spectrum with fainter continuum has these lines in emission. The emission lines of N V and Si IV are an…

Low-resolution MG II H and K observations of solar type stars.

Barry, D. C.; Schoolman, S. A.

Observations with the International Ultraviolet Explorer (IUE) have made possible a comparison between chromospheric radiative loss rates in the Mg II h and k lines and the Ca II H and K lines. Observations made by Stencel et al. (1980) confirm the findings of Linsky et al. (1979) that the chromospheric radiative loss rates in h and k and H and K …
