Abstract:
Despite its fundamental importance, a reliable estimate of the
Galactic nova rate has remained elusive. Here, the overall Galactic
nova rate is estimated by extrapolating the observed rate for novae
reaching m≤2 to include the entire Galaxy using a two component disk
plus bulge model for the distribution of stars in the Milky Way. The
present analysis improves on previous work by considering important
corrections for incompleteness in the observed rate of bright novae
and by employing a Monte Carlo analysis to better estimate the
uncertainty in the derived nova rates. Several models are considered
to account for differences in the assumed properties of bulge and disk
nova populations and in the absolute magnitude distribution. The
simplest models, which assume uniform properties between bulge and
disk novae, predict Galactic nova rates of ∼50 to in excess of 100 per
year, depending on the assumed incompleteness at bright magnitudes.
Models where the disk novae are assumed to be more luminous than bulge
novae are explored, and predict nova rates up to 30% lower, in the
range of ∼35 to ∼75 per year. An average of the most plausible models
yields a rate of 50-23+31yr-1, which is arguably the best
estimate currently available for the nova rate in the Galaxy.
Virtually all models produce rates that represent significant
increases over recent estimates, and bring the Galactic nova rate into
better agreement with that expected based on comparison with the
latest results from extragalactic surveys.
Description:
In this paper, we reconsider the analysis presented in Shafter
(2002AIPC..637..462S 2002AIPC..637..462S) and Shafter (1997ApJ...487..226S 1997ApJ...487..226S) by conducting
Monte Carlo simulations to estimate the global Galactic nova rate and
its uncertainty. The revised analysis includes the increased sample of
Galactic novae available since 2000. From 1900 to the end of 2015
there have been a total of ∼250 Galactic novae discovered brighter
than m=10, and we have compiled a list of these novae in Table 1.
