Abstract:
The results of the first synoptic survey of novae in the barred spiral
and starburst galaxy, M83 (NGC 5236), are presented. A total of
19 novae and one background supernova were discovered during the
course of a nearly 7 year survey comprised of over 200 individual
nights of observation between 2012 December 12 and 2019 March 14.
After correcting for the limiting magnitude and the spatial and
temporal coverage of the survey, the nova rate in M83 was found to be
R=19+5-3yr-1. This rate, when normalized to the K-band
luminosity of the galaxy, yields a luminosity-specific nova rate,
νK=3.0+0.9-0.6x10-10yr-1L☉,K-1. The spatial
distribution of the novae is found to be more extended than the
overall galaxy light suggesting that the observed novae are likely
dominated by a disk population. This result is consistent with the
observed novae light curves, which reveals that the M83 novae are on
average more luminous at maximum light and fade faster when compared
with novae observed in M31. Generally, the more luminous M83 novae
were observed to fade more rapidly, with the complete sample being
broadly consistent with a linear maximum magnitude versus rate of
decline relation.
Description:
Our survey for novae in M83 spanned approximately 7 years between
2012-December-12 and 2019-March-14. During this time we acquired a
total of 205 nightly images of the galaxy. All observations were
acquired with the 1.54m Danish reflector at the La Silla Observatory.
The vast majority of our images were taken through a broadband R
filter, with occasional exposure taken through an I filter.
