Titolo: | On the possible existence of two classes of progenitors for classical novae | Autori: | DELLA VALLE, Massimo Bianchini, A. Livio, M. ORIO, Marina |
Data pubblicazione: | 1992 | Rivista: | ASTRONOMY & ASTROPHYSICS | Numero: | 266 | Da pagina:: | 232 | Abstract: | In a 'fiducial sample' of classical novae for which the distances are established independently of the maximum magnitude vs rate of decline relationship, novae with t2 equal to or less than 12 days are found to be concentrated at low heights above the galactic plane. At the same time, low amplitude and slow novae are found to extend all the way to z about 1000 pc. This is consistent with the statistics of extra-galactic novae. We discuss how the distribution of novae of different speed classes may indicate that the progenitors of classical novae belong to two different classes. | URI: | http://hdl.handle.net/20.500.12386/32656 | URL: | https://ui.adsabs.harvard.edu/abs/1992A%26A...266..232D/abstract | ISSN: | 0004-6361 | Bibcode ADS: | 1992A&A...266..232D | Fulltext: | open |
