The Sensitivity of Nucleosynthesis in Type I X-ray Bursts to Thermonuclear Reaction-Rate Variations
Anuj Parikh, Jordi Jose, Fermin Moreno +1
We examine the sensitivity of nucleosynthesis in Type I X-ray bursts to variations in nuclear rates. As a large number of nuclear processes are involved in these phenomena -with th…
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…
Influence of new reaction rates on 18F production in novae
Alain Coc, Margarita Hernanz, Jordi Jose +1
Gamma-ray emission from classical novae is dominated, during the first hours, by positron annihilation resulting from the beta decay of radioactive nuclei. The main contribution co…
Possibility of the detection of classical novae with the shield of the INTEGRAL-spectrometer SPI
P. Jean, J. Gomez-Gomar, M. Hernanz +7
The shield of the INTEGRAL spectrometer provides a large detection area with a wide field-of-view. Calculations have been performed to check whether the temporal analysis of the co…
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…
