Studies of the Diffuse Interstellar Bands. III. HD 183143
L. M. Hobbs, D. G. York, J. A. Thorburn +8
Echelle spectra of HD 183143 [B7Iae, E(B-V) = 1.27] were obtained on three nights, at a resolving power R = 38,000 and with a signal-to-noise ratio ~1000 at 6400 A in the final, co…
The Red Rectangle: Its Shaping Mechanism and its Source of Ultraviolet Photons
Adolf N. Witt, Uma P. Vijh, L. M. Hobbs +3
The proto-planetary Red Rectangle nebula is powered by HD 44179, a spectroscopic binary (P = 318 d), in which a luminous post-AGB component is the primary source of both luminosity…
A Catalog of Diffuse Interstellar Bands in the Spectrum of HD 204827
L. M. Hobbs, D. G. York, T. P. Snow +8
Echelle spectra of the double-lined spectroscopic binary HD 204827 were obtained on five nights, at a resolving power R = 38,000 and with a S/N ratio = 750 near 6000 A in the final…
Abundances and Behavior of 12CO, 13CO, and C2 in Translucent Sight Lines
P. Sonnentrucker, D. E. Welty, J. A. Thorburn +1
Using UV spectra obtained with FUSE, HST, and/or IUE, we determine interstellar column densities of 12CO, 13CO, and/or C_2 for ten Galactic sight lines with 0.37<E(B-V)<0.72. The N…
VLT/UVES Observations of Interstellar Molecules and Diffuse Bands in the Magellanic Clouds
D. E. Welty, S. R. Federman, R. Gredel +2
We discuss the abundances of interstellar CH, CH+, and CN in the Magellanic Clouds (MC), derived from spectra of 7 SMC and 13 LMC stars obtained (mostly) with the VLT/UVES. CH and/…
Unusually Weak Diffuse Interstellar Bands toward HD 62542
T. P. Snow, D. E. Welty, J. Thorburn +4
As part of an extensive survey of diffuse interstellar bands (DIBs), we have obtained optical spectra of the moderately reddened B5V star HD 62542, which is known to have an unusua…
