Determining reliable distances to classical novae is a challenging but crucial step in deriving
their ejected masses and explosion energetics. Here we combine radio expansion …

Time-series spectra of the near-infrared 1.6 μm region have been obtained for five of the six
known D-type symbiotic novae. The spectra map the pulsation kinematics of the Mira …

Narrowband images of 51 symbiotic stars were obtained at the ESO and ORM observatories
to search for resolved optical nebulae. Ionized nebulae much larger than previously known …

Abstract Very Large Array surface brightness and spectral index maps of the evolving
extended emission of the triple symbiotic star CH Cygni are presented. These are derived …

We present narrowband images and [Nii] lambda 658.3 nm spectra, obtained under sub-
arcsec seeing conditions, of the extended nebulae around the symbiotic Miras He 2-147 …

This paper investigates the Raman-scattered O vi emission lines λλ6825, 7082 in symbiotic
binaries using Monte Carlo simulations. The simulations calculate the scattering path of O vi …

We present radio imaging observations of the 1998 outburst of the peculiar emission-line
star CI Cam, taken~ 1, 4, 75, 82, 93, 163, and 306 days after the beginning of the 1998 …

We present new formulations of binary colliding wind models appropriate to symbiotic star
systems. The derived models differ from previous formulations in assuming mixing of the …

Abstract VLA, MERLIN and Hubble Space Telescope imaging observations of the extended
regions of the symbiotic system CH Cygni are analysed. These extensions are evidence of a …

We present spectropolarimetric observations of the symbiotic Mira V1016 Cygni which cover
the broad emission features at λ6825 and λ7082. The λ6825 line, which is due to Raman …
