Context. Classical novae are expected to emit gamma rays during their explosions. The most important contribution to the early gamma-ray emission comes from the annihilation with electrons of the positrons generated by the decay of 13 Na nd 18 F. The photons are expected to be down-scattered to a few tens of keV, and the emission is predicted to occur some days before the visual discovery and to last∼2 days. Despite a number of attempts, no positive detections of such emission have been made…

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
Swift observations of 52 Galactic/Magellanic Cloud novae are presented indicating that additional factors beyond the white dwarf mass and binary separation play important roles in the evolution of a nova outburst and two optical phenomena are confirmed that are correlated with strong, soft X-ray emission which can be used to further increase the efficiency ofX-ray campaigns.
Infrared Spectroscopy of the Recent Outburst in V1047 Cen (Nova Centauri 2005)
Fourteen years after its eruption as a classical nova (CN), V1047 Cen (Nova Cen 2005) began an unusual re-brightening in 2019 April. The amplitude of the brightening suggests that this is a dwarf
Novae ejecta as colliding shells
Following on our initial absorption-line analysis of fifteen novae spectra we present additional evidence for the existence of two distinct components of novae ejecta having different origins. As
Positron astrophysics and areas of relation to low-energy positron physics
I briefly review our general knowledge of positron astrophysics, focusing mostly on the theoretical and modelling aspects. The experimental/observational aspects of the topic have recently been
A Prediction Formula of Supersoft X-ray Phase of Classical Novae
On the basis of the recently developed universal decline law of classical novae, we propose prediction formulae for supersoft X-ray on and off times, i.e., t{sub X-on} = (10 +- 1.8)t{sub 3} days and
New 34CI proton-threshold states and the thermonuclear 33S(p,γ)34Cl rate in ONe novae
Analysis of presolar grains in primitive meteorites has shown isotopic ratios largely characteristic of the conditions thought to prevail in various astrophysical environments. A possible indicator
A new catalogue of Galactic novae: investigation of the MMRD relation and spatial distribution
In this study, a new Galactic novae catalogue is introduced collecting important parameters of these sources such as their light curve parameters, classifications, full width half maximum (FWHM) of
Binary Systems and Their Nuclear Explosions
The nuclear energy supply of a typical star like the Sun would be ~ 1052 erg if all the hydrogen could be incinerated into iron peak elements. Since the gravitational binding energy is ~ 1049 erg, it
What do (and don't) we understand about explosive nucleosynthesis?
Isotopic abundances reflect both nuclear structure and environmental history. Observations are providing new evidence that is helping us to understand astrophysical phenomena, the chemical history of


Gamma-Ray Emission from Novae Related to Positron Annihilation: Constraints on its Observability Posed by New Experimental Nuclear Data.
Smaller ejected masses of 18F are predicted, leading to smaller emitted fluxes in the 20-511 keV range and shorter detectability distances, which relies critically on a good knowledge of reaction rates relevant to 18F destruction.

Gamma‐ray emission from individual classical novae
Classical novae are important producers of radioactive nuclei, such as 7 Be, 13 N, 18 F, 22 Na and 26 Al. The disintegration of these nuclei produces positrons (except for 7 Be) that through
