O, Na, Ba and Eu abundance patterns in open clusters
B. T. MacLean, G. M. De Silva, J. Lattanzio
Open clusters are historically regarded as single-aged stellar populations representative of star formation within the Galactic disk. Recent literature has questioned this view, ba…
On the Numerical Treatment and Dependence of Thermohaline Mixing in Red Giants
John Lattanzio, Lionel Siess, Ross Church +5
In recent years much interest has been shown in the process of thermohaline mixing in red giants. In low and intermediate mass stars this mechanism first activates at the position…
Super and massive AGB stars - IV. Final fates - Initial to final mass relation
Carolyn L. Doherty, Pilar Gil-Pons, Lionel Siess +2
We explore the final fates of massive intermediate-mass stars by computing detailed stellar models from the zero age main sequence until near the end of the thermally pulsing phase…
Stellar origin of the 182Hf cosmochronometer and the presolar history of solar system matter
Maria Lugaro, Alexander Heger, Dean Osrin +7
Among the short-lived radioactive nuclei inferred to be present in the early solar system via meteoritic analyses, there are several heavier than iron whose stellar origin has been…
Lithium abundances in globular cluster giants: NGC 6218 (M12) and NGC 5904 (M5)
Valentina D'Orazi, George C. Angelou, Raffaele G. Gratton +5
Convergent lines of evidence suggest that globular clusters host multiple stellar populations. It appears that they experience at least two episodes of star formation whereby a fra…
The Dawes Review 2: Nucleosynthesis and stellar yields of low and intermediate-mass single stars
Amanda I. Karakas, John C. Lattanzio
The chemical evolution of the Universe is governed by the chemical yields from stars, which in turn is determined primarily by the initial stellar mass. Even stars as low as 0.9Msu…
