MESA Isochrones and Stellar Tracks. II. Models with alpha-enhanced chemical composition
A Dotter, E Bauer, MJ Park +4
We update and expand the MESA Isochrones and Stellar Tracks (MIST) database to include variations in the alpha-capture elements, specifically [alpha/Fe]=-0.2, 0, +0.2, +0.4, and +0…

3D Simulations Demonstrate Propagating Thermohaline Convection for Polluted White Dwarfs
Imogen G. Cresswell, Adrian E. Fraser, Evan B. Bauer +2
Polluted white dwarfs (WDs) with small surface convection zones deposit significant concentrations of heavy elements to the underlying radiative interior, presumably driving thermo…
