Upper limits of the Na yield from O-Ne nova
P. Jean, J. Knödlseder, P. von Ballmoos +3
The radioactive isotope Na is one of the primary tracer isotopes that may potentially be detectable by gamma-ray spectroscopy. This isotope is predicted to be produced in ON…
Prospects for detectability of classical novae with INTEGRAL
M. Hernanz, J. Gomez-Gomar, J. Jose +1
Classical novae are potential gamma-ray emitters, both in lines and in a continuum. Continuum emission (at energies between 20-30 and 511 keV) and line emission at 511 keV are rela…
Explosive nucleosynthesis
M. Hernanz
Many radioactive nuclei relevant for gamma-ray astrophysics are synthesized during explosive events, such as classical novae and supernovae. A review of recent results of explosive…
Galactic distribution of 1.275 MeV emission from O-Ne novae
P. Jean, M. Hernanz, J. Gomez-Gomar +1
Modelisations of galactic 1.275 MeV emission produced by the decay 22Na have been performed for several frequency-spatial distributions of ONe novae. Recent results of nova rates a…
Gamma-ray emission of classical novae and its detectability by INTEGRAL
M. Hernanz, J. Gomez-Gomar, J. Jose +2
A lot of information concerning the mechanism of nova explosions will be extracted from the possible future observations with INTEGRAL. In order to be prepared for this task, we ar…
On the ^7 Li and ^7 Be synthesis in novae
M. Hernanz, J. Jose, A. Coc +1
The production of ^7 Li and ^7 Be during the explosive hydrogen-burning that occurs in nova explosions is computed by means of a hydrodynamic code able to treat both the accretion…
