The mid-ultraviolet spectrum of EPS Aur.

Bibcode: 1982A&AS...50..233C

Kondo, Y.; Castelli, F.; Hoekstra, R.

An LTE synthetic spectrum with Te = 7800 K and log g = 1 has been computed for the 2455-to-3230 A range of Epsilon Aurigae (F0 1a). This has been compared with the spectra observed with 0.2 A resolution with the IUE experiment and with 0.1 A resolution with the BUSS experiment. As a consequence of this comparison, identifications and abundance val…

UV and visible photometry of the brightest Pleiades stars.

Bibcode: 1982A&AS...47..547G

Mauron, N.; Golay, M.

This paper describes 7-color photometric observations of the brightest stars in the Pleiades taken over the last 20 years. These data are analyzed in conjunction with UV photometric and spectroscopic observations made with the OAO-II, IUE satellites and a balloon-borne photometer. Accurate determinations of the interstellar extinction are obtained…

Ultraviolet spectra of planetary nebulae. VIII. The C/O abundance ratio in the ring nebula.

DOI: 10.1093/mnras/199.1.15P Bibcode: 1982MNRAS.199P..15F

Flower, D. R.

The Ring nebula (NGC 6720) has been observed with the International Ultraviolet Explorer satellite. Measurements of line intensities at a position on the ring, offset from the central star, lead to a value of the abundance ratio C/O approximately 1.2, a result which is insensitive to the adopted value of the electron temperature in the nebula.

The graphite rich Cepheus OB3 association.

Bibcode: 1982A&A...111..130B

Panagia, N.; Perinotto, M.; Barsella, B.

The four optically brightest stars of the Cepheus OB 3 association have been observed with the IUE satellite in the spectral range 1150-3200 A. The extinction suffered by the stars has been investigated. Both the shape of the bump at approximately 2200 A and the behavior of the extinction at longer wavelengths are close to those of the mean inters…

Ultraviolet shell formation at V1016 Cygni.

DOI: 10.1086/183926 Bibcode: 1982ApJ...263L..69F

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…

Dependence on Reddening of Interstellar Column Densities in the Direction of O-Stars

DOI: 10.1007/BF00651473 Bibcode: 1982Ap&SS..82..173M

Mentese, H. H.

We have investigated 14 O-type stars with IUE high resolution SWP spectra in order to improve the relations of element depletions withE(B-V), and to look for other possible relations with two stellar parameters: namely, the rate of mass loss and rotational velocity. The stars were chosen so as to cover several directions in the Galaxy, as well as …

Heck, A.; Russo, G.; Eichendorf, W. +2 more

Ultraviolet IUE spectra, optical 12 A/mm red and blue spectra, optical BV photometry and infrared JHKL photometry of the 7.5-d classical Cepheid R Muscae equals HD 110 311 are presented and discussed together with some earlier photometric and radial velocity data. Using the CORS method, a newly derived radius is given, as well as new values for ef…

A search for medium Z elements in the ultraviolet spectrum of kap Cnc.

Bord, D. J.; Davidson, J. P.

The method of wavelength coincidence statistics is used to search for selected elements having Z values in the 12-40 range in the long wavelength (1960-3230 A) IUE spectrum of the Hg-Mn star Kappa Cancri. Evidence to support the identifications of the even Z elements Mg, Si, Ca, Sr, and Zr, in addition to the odd Z element Cl, has been found. Resu…
