Descripción
For the past 6 years the authors have been measuring the radial velocity
of the M-giant component of symbiotic stars with high dispersion echelle
spectrographs. The orbital solutions derived from these velocity curves
allow the approximate size of the binary to be determined, and also
provide insight into the origin of the photometric variations seen in
these stars. For most of the stars, the photometric variations are due
to eclipse or reflection effects (two notable exceptions are Z And and
RW Hya). Stars which may be near to filling their Roche lobes are TX
CVn, Z And, EG And, UV Aur, and CI Cyg. Stars which do not appear to
fill their Roche lobes are AG Dra, RW Hya, and AG Peg.
