Magnetic Bubbles and Extramixing in Stars (2008)
Wasserburg, Gerald J., Busso, Maurizio
The possible role of magnetic flux tubes in transporting matter from near the H shell through the radiative zone and into the convective envelope is explored. It is shown that the required rates of...
Can Extra Mixing in RGB and AGB Stars Be Attributed to Magnetic Mechanisms? (2007)
Busso, Maurizio, Wasserburg, Gerald J., Nollett, Kenneth M., Calandra, Andrea
It is known that there must be some weak form of transport (called cool bottom processing, or CBP) acting in low mass RGB and AGB stars, adding nuclei, newly produced near the hydrogen-burning shell,...
Low-mass lithium-rich AGB stars in the Galactic bulge: evidence for Cool Bottom Processing? (2007)
Uttenthaler, Stefan, Lebzelter, Thomas, Palmerini, Sara, Busso, Maurizio, Aringer, Bernhard, Lederer, Michael T.
Context: The stellar production of the light element lithium is still a matter of debate. Aims: We report the detection of low-mass, Li-rich Asymptotic Giant Branch (AGB) stars located in the...
Submillimetre/TeraHertz Astronomy at Dome C with CEA filled bolometer array (2007)
Minier, Vincent, Durand, Gilles, Lagage, Pierre-Olivier, Talvard, Michel, Travouillon, Tony, Busso, Maurizio, ...
Submillimetre/TeraHertz (e.g. 200, 350, 450 microns) astronomy is the prime technique to unveil the birth and early evolution of a broad range of astrophysical objects. A major obstacle to carry out...

Technetium and the third dredge up in AGB stars II. Bulge stars (2006)
Uttenthaler, Stefan, Hron, Josef, Lebzelter, Thomas, Busso, Maurizio, Schultheis, Mathias, Kaeufl, Hans Ulrich
We searched for Technetium (Tc) in a sample of bright oxygen-rich asymptotic giant branch (AGB) stars located in the outer galactic bulge. Tc is an unstable element synthesised via the s-process in...
Busso, Maurizio, Ciprini, Stefano, Marcucci, Francesca
We discuss some open problems in the understanding of the Early Solar System abundances of short-lived radioactive isotopes, and the important clarification expected on this matter by precise...
Ciprini, Stefano, Busso, Maurizio
A preliminary analysis of the data from the MSX space infrared satellite, seems to confirm that the [8.8]-[12.5] micron color index is well correlated with the mass-loss rates in carbon stars of our...
Lead: Asymptotic Giant Branch production and Galactic Chemical Evolution (2000)
Travaglio, Claudia, Gallino, Roberto, Busso, Maurizio, Gratton, Raffaele
The enrichment of Pb in the Galaxy is followed in the framework of a detailed model of Galactic chemical evolution that already proved adequate to reproduce the chemical enrichment of O and of the...
S- and R-Process Elements in Two Very Metal-Poor Stars (2000)
Sean G. Ryan, John E. Norris, Timothy C, Roberto Gallino, Maurizio Busso
. New measurements of neutron-capture elements are presented for two very metal-poor stars ([Fe/H] Gamma3). One (LP 625-44) has an s-process signature believed to be due to mass transfer from a...
s- and r-process elements in two very metal-poor stars (2000)
Ryan, Sean G., Aoki, Wako, Blake, Lisa A. J., Norris, John E., Beers, Timothy C., Gallino, Roberto, ...
New measurements of neutron-capture elements are presented for two very metal-poor stars ([Fe/H] ~ -3). One (LP 625-44) has an s-process signature believed to be due to mass transfer from a...
Lugaro, Maria, Gallino, Roberto, Busso, Maurizio, Amari, Sachiko, Zinner, Ernst
Mainstream presolar SiC grains from primitive meteorites show a clear s-process signature in the isotopic composition of heavy trace elements. These grains most likely condensed in the winds of a...
