3D hydrodynamical simulations of a proton ingestion episode in a low-metallicity asymptotic giant branch star
Richard J. Stancliffe, David S. P. Dearborn, John C. Lattanzio +2
We use the 3D stellar structure code DJEHUTY to model the ingestion of protons into the intershell convection zone of a 1 solar mass asymptotic giant branch star of metallicity Z=1…
Compulsory Deep Mixing of 3He and CNO Isotopes in the Envelopes of low-mass Red Giants
Peter P. Eggleton, David S. P. Dearborn, John C. Lattanzio
Three-dimensional stellar modeling has enabled us to identify a deep-mixing mechanism that must operate in all low mass giants. This mixing process is not optional, and is driven b…
Three Dimensional Simulations of the Core Helium Flash - with Rotation
John Lattanzio, David Dearborn, Peter Eggleton +1
We continue our study of the core helium flash using the three dimensional hydrodynamics code Djehuty. Continuing from earlier calculations, we now take relaxed 3D configurations a…
3D Numerical Experimentation on the Core Helium Flash of low-mass Red Giants
David S. P. Dearborn, John C. Lattanzio, Peter P. Eggleton
We model the core helium flash in a low-mass red giant using Djehuty, a fully three-dimensional (3D) code. The 3D structures were generated from converged models obtained during th…
Galactic Evolution Of D And 3He Including Stellar Production Of 3He
David S. P. Dearborn, Gary Steigman, Monica Tosi
New stellar models which track the production and destruction of He (and D) have been evolved for a range of stellar masses , metallicities $(0.…
Possible Systematic Decreases in the Age of Globular Clusters
X. Shi, D. N. Schramm, D. S. P. Dearborn +1
The ages of globular clusters inferred from observations depends sensitively on assumptions like the initial helium abundance and the mass loss rate. A high helium abundance (e.g.,…
