Our Maestro studies have appeared in two papers:
- Low Mach Number Models of Convection in Helium Shells on Sub-Chandrasehkar White Dwarfs. I. Methodology, Zingale, M., Nonaka, A., Almgren, A. S., Bell, J. B., Malone, C. M., & Orvedahl, R. J. 2013, ApJ, 764, 96
- Low Mach Number Modeling of Convection in Helium Shells on Sub-Chandrasekhar White Dwarfs II: Bulk Properties of SimpleModels, Jacobs, A. M., Zingale, M., Nonaka, A., Almgren, A. S., & Bell, J. B. 2016, ApJ, 827, 84
The first paper demonstrated the ability of Maestro to model the convection leading up to ignition.
An animation of the radial velocity in the helium layer. Notice the development of a granulation-like pattern.
Our follow-on study explored a wide range of different initial conditions, varying both the white dwarf mass and the mass of the helium layer.
