We enhance the treatment of crystallization for models of white dwarfs (WDs) in the stellar
evolution software Modules for Experiments in Stellar Astrophysics (MESA) by implementing …

We present a spectroscopic survey of 248 white dwarf candidates within 40 pc of the Sun; of
these 244 are in the Southern hemisphere. Observations were performed mostly with the …

It has been recently suggested that white dwarfs generate magnetic fields in a process
analogous to the Earth. The crystallization of the core creates a compositional inversion that …

We investigate heat transport associated with compositionally driven convection driven by
crystallization at the ocean–crust interface in accreting neutron stars, or growth of the solid …

ABSTRACT A convective dynamo operating during the crystallization of white dwarfs is one
of the promising channels to produce their observed strong magnetic fields. Although the …

We present a comprehensive overview of a volume-complete sample of white dwarfs
located within 40 pc of the Sun, a significant proportion of which were detected in Gaia Data …

ABSTRACT A new class of white dwarfs, dubbed DAHe, that present Zeeman-split Balmer
lines in emission has recently emerged. However, the physical origin of these emission lines …

Two recently discovered white dwarfs, WD J041246. 84+ 754942.26 and WD J165335. 21−
100116.33, exhibit Hα and Hβ Balmer line emission similar to stars in the emerging DAHe …

The origin of strong () magnetic fields in white dwarfs has been a puzzle for decades.
Recently, a dynamo mechanism operating in rapidly rotating and crystallizing white dwarfs …

The origin of large magnetic fields (≳ 10 6 G) in isolated white dwarfs is not clear. One
possible explanation is that crystallization of the star's core drives compositional convection …
