Cassini observations of the Interplanetary Medium Upstream of Saturn and their relation to the Hubble Space Telescope aurora data
Dougherty, M. K.; Jackman, C. M.; Clarke, J. T. +3 more
We present Cassini magnetometer and plasma data for the January 2004 ‘solar wind campaign’ in which the particles and fields instruments monitored the solar wind and interplanetary magnetic field, while the Hubble Space Telescope (HST) simultaneously observed the UV aurora in Saturn’s southern ionosphere. Clear structuring is evident in the data w…
Ceres: High-resolution imaging with HST and the determination of physical properties
Russell, C. T.; Stern, S. A.; Young, E. F. +4 more
Nine HST orbits have been used to image Ceres using the High Resolution Camera of the Advanced Camera for Surveys. Two hundred and fifty-nine images in three filters (F555W, F330W and F220W) were obtained covering the entire surface. Two visible features are readily apparent, a dark patch and a bright point. The bright spot was suitable for contro…
Compact X-ray binaries in and out of core collapsed globulars
Grindlay, Jonathan E.
We review new Chandra and HST observations of the core collapsed cluster NGC 6397 as a guide to understanding the compact binary (CB) populations in core collapse globulars. New cataclysmic variables (CVs) and main sequence chromospherically active binaries (ABs) have been identified, enabling a larger sample for comparison of the Lx, F…
Far ultraviolet spectroscopy of (non-magnetic) cataclysmic variables
Long, Knox S.
HST and FUSE have provided high signal-to-noise, high-resolution spectra of a variety of cataclysmic variables and have allowed a detailed characterization of FUV emission sources in both high and low states. Here, I describe how this has advanced our understanding of non-magnetic CVs. In the high state, the FUV spectra are dominated by disk emiss…
