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…
Djehuty, a Code for Modeling Stars in Three Dimensions
G. Bazan, D. S. P. Dearborn, D. D. Dossa +10
Current practice in stellar evolution is to employ one-dimensional calculations that quantitatively apply only to a minority of the observed stars (single non-rotating stars, or we…
Stellar and dynamical evolution within triple systems
P. P. Eggleton, L. G. Kiseleva
About 5-15% of stellar systems are at least triple. About 1% of systems with a primary of $\tgs 1 \Mscun$ are triple with a {\it longer} peri od that is less than 30y, and so may i…
