Eccentricities of millisecond pulsars with intermediate-mass progenitors
Hagai Bareli, Sivan Ginzburg
One channel to form millisecond pulsars with CO white dwarf companions is through the stable Roche-lobe overflow of intermediate-mass ($3\,{\rm M}_\odot\lesssim M\lesssim 5\,{\rm M…
Double-faced white dwarfs and the magnetic inhibition of convection
Sivan Ginzburg
About one in five white dwarfs undergoes spectral evolution from a helium atmosphere to hydrogen and then back to helium. These short-lived hydrogen envelopes - the result of resid…
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 …
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…
