Abstract:To test the hypothesis about the existence of two different subsystems of novae in the Galaxy, disk and bulge novae, we have constructed the spatial distribution of 64 novae in z coordinate. A large number of fast novae, believed to be disk novae, are at a considerable distance from the Galactic plane (up to z ~ 3700 pc), which cannot be explained by the photometric measurement errors. Slow novae, believed to be bulge novae, show a higher concentration to the Galactic plane (z ? 1700 pc). The application of the Kolmogorov-Smirnov test has shown that the hypothesis of two populations is valid with a probability of 95.6%.
