|High-Speed Stellar Ejecta|
We study a range of stellar objects which eject material at high-speeds.
These include close active binaries, symbiotic stars, X-ray
binaries, novae, and Wolf-Rayet binaries.
We combine observations using facilities such as
MERLIN, the VLA,
VLBI, HST with hdyrodynamic modelling
of the ejected material.
A VLA image of the symbiotic star CH Cygni in 1986, two years after a major nova-like outburst. The two blobs seen in the image are material ejected in the initial outburst. We have recently shown that the two outer blobs are non-thermal radio emitters whilst the central component is thermal.
Since then, the group has monitored this star with MERLIN, the VLA and the HST.
