We survey our understanding of classical novae—nonterminal, thermonuclear eruptions on
the surfaces of white dwarfs in binary systems. The recent and unexpected discovery of GeV …

Interacting binaries in which a white dwarf accretes material from a companion—cataclysmic
variables (CVs) in which the mass donor is a Roche-lobe filling star on or near the main …

Recurrent novae are repeating thermonuclear explosions in the outer layers of white dwarfs,
due to the accretion of fresh material from a binary companion. The shock generated when …

This paper presents a catalog of high-energy γ-ray sources detected in the first two years of
the Fermi Gamma-ray Space Telescope mission by the Large Area Telescope (LAT). It is the …

Classical novae are cataclysmic binary star systems in which the matter of a companion star
is accreted on a white dwarf,. Accumulation of hydrogen in a layer eventually causes a …

After initial claims and a long hiatus, it is now established that several binary stars emit high-
(0.1–100 GeV) and very high-energy (> 100 GeV) gamma rays. A new class has emerged …

A classical nova results from runaway thermonuclear explosions on the surface of a white
dwarf that accretes matter from a low-mass main-sequence stellar companion. In 2012 and …

Abstract e-ASTROGAM ('enhanced ASTROGAM') is a breakthrough Observatory space
mission, with a detector composed by a Silicon tracker, a calorimeter, and an …

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 …

The physical mechanism driving mass ejection during a nova eruption is still poorly
understood. Possibilities include ejection in a single ballistic event, a common-envelope …
