Forging neon-distilling white dwarfs in the stellar engulfments of helium white dwarfs
Nicholas Z. Rui, Jim Fuller
Once carbon--oxygen white dwarfs cool sufficiently, they crystallize from the inside out. If the white dwarf is rich enough in , these crystallized solids are b…
Seismology and diffusion of ultramassive white dwarf magnetic fields
Daniel Blatman, Nicholas Z. Rui, Sivan Ginzburg +1
Ultramassive white dwarfs (UMWDs; defined by masses ) are prime targets for seismology, because they pass through the ZZ Ceti instability strip at the s…
It's not just a phase: oblique pulsations in magnetic red giants and other stochastic oscillators
Nicholas Z. Rui, Jim Fuller, J. M. Joel Ong
Magnetic fields play a significant role in stellar evolution. In the last few years, asteroseismology has enabled the measurement of strong magnetic fields --$10^6\,\mathrm{G…
Magnetic dynamos powered by white dwarf superficial convection
Rom Yaakovyan, Sivan Ginzburg, Jim Fuller +1
When the effective temperature of a cooling white dwarf drops below the ionization limit, it develops a surface convection zone that may generate a magnetic field …
