Recovery of the old nova V840 Ophiuchi: A carbon rich system.

SCHMIDTOBREICK L., TAPPERT C., BIANCHINI A. and MENNICKENT R.E.

Abstract (from CDS):

We present optical spectroscopy and multi colour photometry of the old nova V840 Oph. We rediscovered the nova based on its position in the colour-colour diagrams. It stands out as a very blue object with an additional red component. We present the first optical spectroscopy of this candidate and confirm its nova character. Furthermore, V840 Oph has been found as one of very few cataclysmic variables showing CIV emission at λ=580/1nm. From the analysis of the carbon lines it seems probable that V840 Oph contains actually a carbon-rich secondary star. So far, only the nova-like QU Car has been known to have such a companion. We furthermore find spectroscopic evidence that V840 Oph has a hot, dense accretion disc or stream and is probably a magnetic system.
