FUSE Measurements of Rydberg Bands of Interstellar CO between 925 and 1150 A

Y. Sheffer, S. R. Federman, B. -G. Andersson

We report the detection of 11 Rydberg bands of CO in FUSE spectra of the sight line toward HD203374A. Eight of these electronic bands are seen in the interstellar medium for the fi…

Further Evidence for Chemical Fractionation from Ultraviolet Observations of Carbon Monoxide

S. R. Federman, David L. Lambert, Yaron Sheffer +4

Ultraviolet absorption from interstellar 12CO and 13CO was detected toward rho Oph A and chi Oph. The measurements were obtained at medium resolution with the Goddard High Resoluti…
