Three-dimensional Hydrodynamical Simulations of a Proton Ingestion Episode in a Low-metallicity Asymptotic Giant Branch Star

Stancliffe, RichardDearborn, DavidLattanzio, JohnHeap, StuartCampbell, S2015-12-100004-637Xhttp://hdl.handle.net/1885/51695We use the three-dimensional (3D) stellar structure code DJEHUTY to model the ingestion of protons into the intershell convection zone of a 1 M ⊙ asymptotic giant branch star of metallicity Z = 10 -4. We have run two simulations: a low-resolution one ofKeywords: convection; hydrodynamics; stars: AGB and post-AGB; stars: carbon; stars: evolution; stars: Population IIThree-dimensional Hydrodynamical Simulations of a Proton Ingestion Episode in a Low-metallicity Asymptotic Giant Branch Star201110.1088/0004-637X/742/2/1212016-02-24
