Abstract

(Abstract only) R Aquarii is a binary with a Mira variable star and a compact companion that is accreting material from the Mira’s wind. We present x-ray and radio observations of the jets in R Aqr from ROSAT, Chandra, and the VLA, showing dynamic changes in their structure over several years. The x-ray spectra of these jets also tell an interesting story about the nature of the excited regions where the x-ray emission originates as well.
