Interstellar Abundances from Absorption-Line Observations with the Hubble Space Telescope
Sembach, Kenneth R.; Savage, Blair D.
The Goddard High-Resolution Spectrograph (GHRS) aboard the Hubble Space Telescope (HST) has yielded precision abundance results for a range of interstellar environments, including gas in the local medium, in the warm neutral medium, in cold diffuse clouds, and in distant halo clouds. Through GHRS studies, investigators have determined the abundanc…
Corotating and Transient Solar Wind Flows in Three Dimensions
Gosling, J. T.
Two types of flows dominate the large-scale structure of the solar wind: corotating flows and transient disturbances. Corotating flows are associated with spatial variability in the coronal expansion and solar rotation, whereas transient disturbances are associated with episodic ejections of material into interplanetary space from coronal regions …
