IUE observations of a luminous M supergiant that exhibits emission continuum in the far ultraviolet.

DOI: 10.1086/158387 Bibcode: 1980ApJ...241..774M

Kafatos, M.; Michalitsianos, A. G.; Hobbs, R. W.

IUE observations of the late-type M supergiant star TV Gem which reveal an intense continuum in the far ultraviolet are discussed. TV Gem was observed in low dispersion in November 1979 and in high and low dispersion in January 1980 by the short and long wavelength cameras of the IUE spectrometer. An essentially featureless UV continuum was obtain…

Balloon and IUE Spectra of Early-Type Stars

Bibcode: 1980IrAJ...14..114B

Bates, B.; Giaretta, D. L.; McCartney, D. J. +1 more

A brief account is given of the balloon flight payloads and an outline is presented of the data reduction from the balloon flights and the IUE observations pertaining to studies of the interstellar gas and to mass loss from super-giant stars. It is noted that the IUE permits extension of the range of observations to the important and weaker MgI an…

On gamma-ray sources, supernova remnants, OB associations, and the origin of cosmic rays.

DOI: 10.1086/157166 Bibcode: 1979ApJ...231...95M

Montmerle, T.

Spatial coincidences between supernova remnants and OB associations or H II regions are sought, and a list of about 30 objects (referred to as 'SNOBs') is obtained. On the basis of COS B data it is found that five, or perhaps six, of 11 as-yet unidentified gamma-ray sources are associated with SNOBs and that as many as three-fourths of the best-id…

Observational evidence for a hot gaseous galactic corona.

Savage, B. D.; de Boer, K. S.

Galactic absorption features observed in high-dispersion far-UV spectra of two Large Magellanic Cloud (LMC) stars obtained with the IUE satellite are discussed. The stars observed were HD 38268 (OB + WN5) and HD 38282 (WN6), which lie at a distance of about 55 kpc and in the galactic direction corresponding to a latitude of about -32 deg and a lon…

Seaton, M. J.

Emission intensities of recombination lines in hydrogenic spectra are known accurately relative to intensities in the free-free radio continuum. For NGC 7027 intensities have been measured for the radio continuum and for H I and He II lines in the wavelength range from 2.17 microns to 1640 A; comparison with the calculated emission intensities giv…

Linsky, J. L.; Basri, G. S.

International Ultraviolet Explorer high-resolution spectra of the Mg II lines at 2796, 2803 A in 15 stars of spectral type G2-M2 including a wide range of luminosities are presented. These spectra are calibrated in absolute flux units at earth and at the stellar surface, and the chromospheric radiative loss rates in the Mg II lines are compared wi…

Ultraviolet observations of AM Herculis with IUE.

DOI: 10.1086/182969 Bibcode: 1979ApJ...230L..95R

Davis, R. J.; Raymond, J. C.; Dupree, A. K. +4 more

Ultraviolet observations of the binary X-ray source AM Herculis from the IUE satellite show strong emission lines of ions from O I to N V, probably originating in photoionized gas, and a continuum which is partially eclipsed in phase with the X-ray eclipse. The emission lines have broad (about 600 km/s) and sharp (about 80 km/s) components at diff…
