Constraining the Ne(,)Mg and Ne(,n)Mg reaction rates using sub-Coulomb -transfer reactions
H. Jayatissa, G. V. Rogachev, V. Z. Goldberg +9
The Ne(,)Mg and Ne(,n)Mg reactions play an important role in astrophysics because they have significant influence on the neutron flux during th…
On the Origin of the Early Solar System Radioactivities. Problems with the AGB and Massive Star Scenarios
D. Vescovi, M. Busso, S. Palmerini +7
Recent improvements in stellar models for intermediate-mass and massive stars are recalled, together with their expectations for the synthesis of radioactive nuclei of lifetime $τ\…
The importance of the 13C(alpha,n)16O reaction in Asymptotic Giant Branch stars
S. Cristallo, M. La Cognata, C. Massimi +9
Low mass Asymptotic Giant Branch stars are among the most important polluters of the interstellar medium. In their interiors, the main component (A>90) of the slow neutron capture…
s-Processing from MHD-induced mixing and isotopic abundances in presolar SiC grains
S. Palmerini, O. Trippella, M. Busso +4
In the past years the observational evidence that s-process elements from Sr to Pb are produced by stars ascending the socalled Asymptotic Giant Branch (or AGB) could not be explai…
Concurrent application of ANC and THM to assess the absolute cross section at astrophysical energies and possible consequences for neutron production in low-mass AGB stars
Oscar Trippella, Marco La Cognata
The reaction is considered to be the main neutron source responsible for the production of heavy nuclides (from to ) through sl…
A Deep Mixing Solution to the Aluminum and Oxygen Isotope Puzzles in Presolar Grains
Sara Palmerini, Oscar Trippella, Maurizio Busso
We present here the application of a model for a mass circulation mechanism in between the H-burning shell and the base of the convective envelope of low mass AGB stars, aimed at s…
-Processing in AGB Stars Revisited. II. Enhanced C Production Through MHD-Induced Mixing
O. Trippella, M. Busso, S. Palmerini +2
Slow neutron captures are responsible for the production of about of elements heavier than iron, mainly, occurring during the asymptotic giant branch phase of low-mass stars…
Isotope Anomalies in the Fe-group Elements in Meteorites and Connection to Nucleosynthesis in AGB Stars
Gerald J. Wasserburg, Oscar Trippella, Maurizio Busso
We study the effects of neutron captures in AGB stars on \oq Fe-group\cqb elements, with an emphasis on Cr, Fe, and Ni. These elements show anomalies in Cr, Fe, and $…
s-Processing in AGB Stars Revisited. I. Does the Main Component Constrain the Neutron Source in the 13C-Pocket?
O. Trippella, M. Busso, E. Maiorca +2
Slow neutron captures at A 85 are mainly guaranteed by the reaction 13C(,n)16O in AGB stars, requiring proton injections from the envelope. These were so far assumed to…
News on the s process from young open clusters
Enrico Maiorca, Laura Magrini, Maurizio Busso +3
Recent spectroscopic measurements in open clusters younger than the Sun, with [Fe/H]>=0, showed that the abundances of neutron-rich elements have continued to increase in the Galax…
