Debye cooling of ultramassive white dwarfs
David Barba-González, Sivan Ginzburg
Recent observations of cold and massive white dwarfs are beginning to probe Debye cooling: an accelerated cooling phase driven by the vanishing heat capacity of the crysta…

Sinking and spreading of metal pollution in magnetic white dwarfs
Elad Shiftan, Sivan Ginzburg
Observations of magnetic polluted white dwarfs indicate that most of them have higher concentrations of metals near the poles compared to lower latitudes. Maintaining such abundanc…

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…
