Systematic and correlated nuclear uncertainties in the i-process at the neutron shell closure N = 82
M. G. Bertolli, F. Herwig, M. Pignatari +1
Nuclear astrophysics simulations aiming to study the origin of the elements in stars require a multitude of nuclear physics input. Both systematic model dependent and statistically…
Relics of ancient post-AGB stars in a primitive meteorite
Manavi Jadhav, Marco Pignatari, Falk Herwig +3
Graphite is one of the many presolar circumstellar condensate species found in primitive meteorites. While the isotopic compositions of low-density graphite grains indicate an orig…
Evidence for Radiogenic Sulfur-32 in Type AB Presolar Silicon Carbide Grains?
Wataru Fujiya, Peter Hoppe, Ernst Zinner +2
We report C, Si, and S isotope measurements on 34 presolar silicon carbide grains of Type AB, characterized by 12C/13C < 10. Nitrogen, Mg-Al-, and Ca-Ti-isotopic compositions were…
NuGrid stellar data set I. Stellar yields from H to Bi for stars with metallicities Z = 0.02 and Z = 0.01
M. Pignatari, F. Herwig, R. Hirschi +16
We provide a set of stellar evolution and nucleosynthesis calculations that applies established physics assumptions simultaneously to low- and intermediate-mass and massive star mo…
Silicon carbide grains of type C provide evidence for the production of the unstable isotope Si in supernovae
M. Pignatari, E. Zinner, M. G. Bertolli +8
Carbon-rich grains are observed to condense in the ejecta of recent core-collapse supernovae, within a year after the explosion. Silicon carbide grains of type X are C-rich grains…
On the internal pollution mechanisms in the globular cluster NGC 6121 (M4): heavy-element abundances and AGB models
Valentina D'Orazi, Simon W. Campbell, Maria Lugaro +3
Globular clusters display significant variations in their light-element content, pointing to the existence of a second stellar generation formed from the ejecta of an earlier gener…
