Nucleosynthesis in stellar flares

V. Tatischeff, J. -P. Thibaud, I. Ribas

Nuclear interactions of ions accelerated at the surface of flaring stars can produce fresh isotopes in stellar atmospheres. Although this nucleosynthesis is not significant for the…

Is 6-Li in metal-poor halo stars produced in situ by solar-like flares?

V. Tatischeff, J. -P. Thibaud

The high 6-Li abundances recently measured in metal-poor halo stars are far above the value predicted by Big Bang nucleosynthesis. They cannot be explained by galactic cosmic-ray i…

Hydrogen Burning of 17-O in Classical Novae

A. Chafa, V. Tatischeff, P. Aguer +10

We report on the observation of a previously unknown resonance at E=194.1+/-0.6 keV (lab) in the 17-O(p,alpha)14-N reaction, with a measured resonance strength omega_gamma(p,alpha)…

Gamma-Ray Line Emission from 7-Li and 7-Be Production by Cosmic-Rays

V. Tatischeff, J. -P. Thibaud, J. Kiener +2

We calculate the total gamma-ray line emission at ~450 keV that accompanies 7-Li and 7-Be production by cosmic-ray interactions, including the delayed line emission at 0.478 MeV fr…

Lithium-6 from Solar Flares

R. Ramaty, V. Tatischeff, J. P. Thibaud +2

By introducing a hitherto ignored Li-6 producing process, due to accelerated He-3 reactions with He-4, we show that accelerated particle interactions in solar flares produce much m…

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…
