Parsec-scale Variations in the 7Li/6Li Isotope Ratio Toward IC 348 and the Per OB 2 Association
D. C. Knauth, C. J. Taylor, A. M. Ritchey +2
Measurements of the lithium isotopic ratio in the diffuse interstellar medium from high-resolution spectra of the LiI λ6708 resonance doublet have now been reported for a number of…
Rubidium in the Interstellar Medium
Kyle M. Walker, S. R. Federman, David C. Knauth +1
We present observations of interstellar rubidium toward o Per, zeta Per, AE Aur, HD 147889, chi Oph, zeta Oph, and 20 Aql. Theory suggests that stable 85Rb and long-lived 87Rb are…
What is the Total Deuterium Abundance in the Local Galactic Disk?
Jeffrey L. Linsky, Bruce T. Draine, H. W. Moos +14
Analyses of spectra obtained with the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite, together with spectra from the Copernicus and IMAPS instruments, reveal an unexplaine…
The Interstellar N/O Abundance Ratio: Evidence for Local Infall?
David C. Knauth, James T. Lauroesch, David M. Meyer
Sensitive measurements of the interstellar gas-phase oxygen abundance have revealed a slight oxygen deficiency ( 15%) toward stars within 500 pc of the Sun as compared to mor…
Spectroscopic study of the long-period dust-producing WC7pd+O9 binary HD192641
L. Lefevre, S. V. Marchenko, S. Lepine +12
We present the results of an optical spectroscopic study of the massive Wolf-Rayet binary WR137. These data cover the dust-formation maximum in 1997. Combining all available measur…
The Interstellar Rubidium Isotope Ratio toward Rho Ophiuchi A
S. R. Federman, David C. Knauth, David L. Lambert
The isotope ratio, 85Rb/87Rb, places constraints on models of the nucleosynthesis of heavy elements, but there is no precise determination of the ratio for material beyond the Sola…
