• # Abstract

Novae refer to close binary systems, where outbursts occur on the white dwarf surface due to thermonuclear runaway. Numerical simulations of nova explosions have shown that the accreted envelopes attain peak temperature of about $4 \times 10^8$ K. The temperature remains at the peak value for about several hundred seconds; this allows nuclear reactions to take place in the ejecta. Theoretical studies predict significant overproduction of few elements, e.g., 17O, 15N, and 13C, with respect to solar abundances. Spectroscopic observations have also confirmed about high metal abundances in novae ejecta. This paper briefly discusses about elemental abundances in novae ejecta predicted by the nucleosynthesis process as well as that found from observations.

Posted on January 27, 2016

Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
