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 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… 
Observations of galactic and extragalactic novae
The recent GAIA DR2 measurements of distances to galactic novae have allowed to re-analyse some properties of nova populations in the Milky Way and in external galaxies on new and more solid
Galactic Extinction: How Many Novae Does It Hide and How Does It Affect the Galactic Nova Rate?
There is a long-standing discrepancy between the observed Galactic classical nova rate of ∼10 yr−1 and the predicted rate from Galactic models of ∼30–50 yr−1. One explanation for this discrepancy is
A Population of Heavily Reddened, Optically Missed Novae from Palomar Gattini-IR: Constraints on the Galactic Nova Rate
The nova rate in the Milky Way remains largely uncertain, despite its vital importance in constraining models of Galactic chemical evolution as well as understanding progenitor channels for Type Ia
Galactic Novae Simulations for the Cherenkov Telescope Array
Context. The recent discovery of classical novae as sources of & 100 MeV gamma-ray emission by the Fermi-LAT has indicated that shocks play an important role in the acceleration of gamma rays at
Classical Novae Masquerading as Dwarf Novae? Outburst Properties of Cataclysmic Variables with ASAS-SN
The unprecedented sky coverage and observing cadence of the All-Sky Automated Survey for SuperNovae (ASAS-SN) has resulted in the discovery and continued monitoring of a large sample of Galactic
A UV and optical study of 18 old novae with Gaia DR2 distances: mass accretion rates, physical parameters, and MMRD
We combine the results of our earlier study of the UV characteristics of 18 classical novae (CNe) with data from the literature and with the recent precise distance determinations from the Gaia
Search for gamma-ray emission from Galactic novae with the Fermi -LAT
Context. A number of novae have been found to emit high-energy gamma rays (>100 MeV). However, the origin of this emission is not yet understood. We report on the search for gamma-ray emission from
Comprehensive models of novae at metallicity Z = 0.02 and Z = 10−4
Novae are the observational manifestations of thermonuclear runaways on the surface of accreting white dwarfs (WDs). Although novae are an ubiquitous phenomenon, their properties at low metallicity
Gamma rays reveal proton acceleration in thermonuclear novae explosions
Classical novae are cataclysmic binary star systems in which the matter of a companion star is accreted on a white dwarf (WD) [1, 2]. Accumulation of the matter in a layer eventually causes a


The Galactic Nova Rate
Despite its fundamental importance and a considerable expenditure of observational effort, a reliable estimate of the Galactic nova rate has remained elusive. In this review recent estimates of the
On the Nova Rate in the Galaxy
The Galactic nova rate is poorly known, with estimates in the literature ranging from as few as 11 to as many as 260 yr-1. At the lower end of the spectrum (≲50 yr-1), the predictions are based on
Exploring the Role of Globular Cluster Specific Frequency on the Nova Rates in Three Virgo Elliptical Galaxies
It has been proposed that a galaxy’s nova rate might be enhanced by the production of nova progenitor binaries in the dense cores of its globular clusters (GCs). To explore this idea, relative nova
Modelling nova populations in galaxies
Theoretical modelling of the evolution of classical and recurrent novae plays an important role in studies of binary evolution, nucleosynthesis and accretion physics. However, from a theoretical
Eruptions of classical novae are possible sources of lithium formation and gamma-ray emission. Nova remnants can also become Type Ia supernovae (SNe Ia). The contribution of novae to these phenomena
On the Spatial Distribution, Stellar Population, and Rate of Novae in M31
As part of a program to study the stellar population of novae, multiepoch Hα surveys of M31 have been undertaken. In the first survey, conducted between 1990 and 1993, a total of 53 novae were
Constraints for cataclysmic binary evolution as derived from space distributions
Space densities and galacticz-distributions of novae, recurrent novae, dwarf novae and symbiotic stars are newly determined and discussed in the context of earlier determinations. The data are then
Novae in External Galaxies: M51, M87, and M101
As part of a program to determine the stellar population of novae, we have conducted a multiepoch Hα survey of the galaxies M51, M87, and M101. A total of nine and 12 novae were detected in the
Optical Imaging of Nova Shells and the Maximum Magnitude-Rate of Decline Relationship
An optical imaging study of 30 recent novae has been undertaken using both ground-based and space-based observations. Resolved shells have been detected around nine objects in the ground-based data,
