Extragalactic Novae and Their Progenitors
… In this thesis, archival Hubble Space Telescope (HST) data are used to search for RG-novae in M31. Many more novae are discovered in M31 each year (~30) than in the Milky Way (~10). Distance determination is a major complication when studying Galactic novae. However, at the distance of M31 all the …
