V445 Puppis

V445 Puppis is a nova variable, where no hydrogen at all was found in the nova. The main star in this system looses quite a lot of matter to its partner, a white dwarf. Because of the remarkable luminosity of the system it is suspected that the white dwarf is close to the Chandrasekhar limit of 1.44 solar masses. So this star is one of the best candidates for a soon-to-come Ia supernova, the more so as at those no hydrogen can be found, too.
