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…
HV2112, a Thorne-Zytkow Object or a Super Asymptotic Giant Branch Star
Christopher A. Tout, Anna N. Zytkow, Ross P. Church +1
The very bright red star HV2112 in the Small Magellanic Cloud could be a massive Thorne-Zytkow Object, a supergiant-like star with a degenerate neutron core. With its luminosity of…
Super and massive AGB stars - III. Nucleosynthesis in metal-poor and very metal-poor stars - Z=0.001 and 0.0001
Carolyn L. Doherty, Pilar Gil-Pons, Herbert H. B. Lau +3
We present a new grid of stellar models and nucleosynthetic yields for super-AGB stars with metallicities Z=0.001 and 0.0001, applicable for use within galactic chemical evolution…
