Far Ultraviolet Spectra of a Non-Radiative Shock Wave in the Cygnus Loop
John Raymond, Parviz Ghavamian, Ravi Sankrit +2
Spatial and spectral profiles of O VI emission behind a shock wave on the northern edge of the Cygnus Loop were obtained with the FUSE satellite. The velocity width of the narrowes…
Intermediate- and High-Velocity Ionized Gas toward zeta Orionis
D. E. Welty, E. B. Jenkins, J. C. Raymond +2
We combine UV spectra obtained with the HST/GHRS echelle, IMAPS, and Copernicus to study the abundances and physical conditions in the predominantly ionized gas seen at high (-105…
Analysis of H2 Emission from Mira B in UV Spectra from HST
Brian E. Wood, Margarita Karovska, John C. Raymond
We analyze Ly-alpha fluoresced H2 lines observed in the UV spectrum of Mira B. We identify 13 different sequences fluoresced by 13 different H2 transitions within the Ly-alpha line…
The Optical Spectrum of the SN 1006 Supernova Remnant Revisited
Parviz Ghavamian, P. Frank Winkler, John C. Raymond +1
We present the deepest optical spectrum acquired to date of Balmer-dominated shocks in the NW rim of SN 1006. We detect the broad and narrow components of H-alpha, H-beta and H-gam…
