I present theoretical light curves of novae and helium novae in EUV and visible bands derived from optically thick wind theory. The EUV light curves are very useful in determining the white dwarf mass and the distance to the star. Helium novae are bright EUV sources but much less luminous in the optical. Identification of helium novae will be observational evidence for the growth of the white dwarf, which will eventually become a Type la supernova. A semi-detached system may be a new progenitor model of Type la supernovae, which is a very bright EUV source with a faint optical counterpart.
