NEW INSIGHT INTO THE SPATIAL-DISTRIBUTION OF NOVAE IN M31

We use a Monte Carlo technique together with a simple model for the di stribution of dust in M31 to investigate the observability and spatial distribution of classical novae in M31. By comparing our model positi ons of novae to the observed positions, we conclude that most M31 nova e come from the disk population, rather than from the bulge population as has been thought. Our results indicate that the M31 bulge-to-disk nova ratio is as low as, or lower than, the M31 bulge-to-disk mass rat io.
