Transport of Magnetic Fields by Thermohaline Convection in Crystallizing White Dwarfs
Nicolas Frazao Fernandes, J. R. Fuentes, Jim Fuller
The origins of strong magnetic fields observed in many white dwarfs are uncertain. Recent observations show that such fields are more common for white dwarfs with crystallized core…
Accretion Rates and Thermohaline Convection in Polluted White Dwarfs
J. R. Fuentes, Matias Castro-Tapia, Jim Fuller +1
Polluted white dwarfs provide a unique window into the composition of exoplanetary material, but interpreting their surface abundances requires a quantitative understanding of the…
Main sequence dynamo magnetic fields emerging in the white dwarf phase
Maria Camisassa, J. R. Fuentes, Matthias R. Schreiber +4
Recent observations of volume-limited samples of magnetic white dwarfs (WD) have revealed a higher incidence of magnetism in older WDs. Specifically, these studies indicate that ma…
A Short Intense Dynamo at the Onset of Crystallization in White Dwarfs
J. R. Fuentes, Matias Castro-Tapia, Andrew Cumming
The origin of large magnetic fields () in isolated white dwarfs is not clear. One possible explanation is that crystallization of the star's core drives co…
Fast and Slow Crystallization-driven Convection in White Dwarfs
Matias Castro-Tapia, Andrew Cumming, J. R. Fuentes
We investigate crystallization-driven convection in carbon-oxygen white dwarfs. We present a version of the mixing length theory (MLT) that self-consistently includes the effects o…
