Abstract

The 2001 outburst of V445 Puppis is an unique object, that shows absence of hydrogen, enrichment of helium and carbon, slow decay of the light curve with a small amplitude. We have calculated theoretical light curves of helium novae to confirm that V445 Pup is the first example of helium nova. From the light curve fitting we conclude that the white dwarf is very massive ≳ 1:33M⊙.
