Abstract

International Ultraviolet Explorer (IUE) studies of Nova V693 CrA showed that its ejecta were enriched in the intermediate mass nuclei from nitrogen to silicon and, thereby defined the ONeMg outburst as a compositional class of novae. The observational studies found that both sodium and aluminum were ∼100 times overabundant with respect to solar material while the theoretical studies predicted that a significant fraction of the sodium and aluminum should be 22 Na and 26 Al. Therefore, nearby ONeMg novae should be observed by COMPTON for possible detection of γ-rays from the decay of 22 Na and novae are probably responsible for the 26 Al observed in the ISM and solar system. Both Nova Her 1991 and Nova Cyg 1992 (the nearest ONeMg nova) are close enough so that they should be observed by COMPTON.
