Dear Claude, It is not an easy task to answer your question. First you should decide which novae interest you. There are classical novae (the primary is most probably a white dwarf), and x-ray novae (the primary is believed to be a compact object). In addition, most novae are found in our galaxy, but there are a few detected in globular clusters / other galaxies. Since there is no professional systematic search for novae (at least I'm not aware of one), most novae are found by very serious amateurs, and we, professionals, appreciate much their work. Exceptions are novae found in systematic surveys (usually aimed for supernovae hunting). The rate of classical nova detections in our galaxy is about 3-4 a year. You can find useful information in the vsnet: http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/novae.html and http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/ Some of the young novae mentioned there and a few more (but not a comprehensive list): 1990 - Sgr, 1991 - V838 Her, Mus (x-ray nova), Sgr 1992 - V1974 Cyg, Sgr 1993 - V703 Cas, V1419 Aql, Sgr 1994 - V2214 Oph, 1995 - V723 Cas, Cen, V1425 Aql, Cir 1996 - Cru, Sgr, 1997 - Sco, 1998 - Mus, Sco, Oph (but it might be a recurrent nova), Sgr, M31 (not in our galaxy). 1999 - V1493 Aql, V382 Vel, V4444 Sgr, V1974 Cyg is for example variable number 1974 in Cygnus. In order to find the discoverer you should search for the first announcement on the nova discovery, usually found in the IAUC. So, either run a search on each nova in the ADS - http://cdsads.u-strasbg.fr/abstract_service.html and check the first IAUC or scan all IAU Circulars since 1990 (this should give you all novae): http://cfa-www.harvard.edu/iauc/RecentIAUCs.html One of the most fertile discoverers of southern novae (Mus 1998, Sgr 1998 and many more) is William Liller, who is an amateur. The japanese have also had many success in this field. It is not easy to find out whether the discoverer is a professional or an amateur. You can email him personally - search his email in the astronomy search engine: http://star-www.rl.ac.uk/astrolist/astrosearch.html but this is mainly for professionals. You can also check his publications in the ADS, and try to conclude from this information. When you'll have a complete list, you can email the vsnet-chat, asking on individuals. I hope that this helps. Regards, Alon ------------------------------------------------------------------------- Dr. Alon Retter Tel. (work) +44-(0)1782-58-3493 Physics Dept.
