Abstract:
CP Pup (Nova Pup 1942) showed outburst and quiescent characteristics
indicating a very massive white dwarf, yet the standard spectroscopic
dynamical analysis assuming an accretion disk yields an extremely low
value for the white dwarf mass. However, some physical parameters and
the accretion geometry are still poorly known.
The nova was spectroscopically monitored between 1988 and 1996. We
analyzed the whole data set in order to re-determine the spectroscopic
period and examine its stability. We also looked for chemical
anomalies in the spectrum.
Description:
We obtained the radial velocity curves for the hydrogen and helium
lines from our last better quality 1996 run. The mean 1996 spectrum
yields information on the chemical composition of the binary. We also
searched the mean period using the multi-year data set.
