Recent observations of volume-limited samples of magnetic white dwarfs (WD) have
revealed a higher incidence of magnetism in older stars. Specifically, these studies indicate …

This review highlights the role of the Gaia space mission in transforming white dwarf
research. These stellar remnants constitute 5%–7% of the local stellar population in volume …

The origin of atmospheric heating in the cool, magnetic white dwarf GD 356 remains
unsolved nearly 40 years after its discovery. This once idiosyncratic star with T eff≈ 7500 K …

Ultramassive white dwarfs with masses M≳ 1.1 M⊙ probe extreme physics near the
Chandrasekhar limit. Despite the rapid increase in observations, it is still unclear how many …

Sufficiently old white dwarfs cool down through a convective envelope that directly couples
their degenerate cores to the surface. Magnetic fields may inhibit this convection by …

Context. There are several symbiotic stars (eg, BF Cyg, Z And, and FN Sgr) in which periodic
signals of tens of minutes have been detected. These periods have been interpreted as the …

We studied the thermal evolution of the central region of a 0.9 M⊙ C/O white dwarf at the
initial stage of ion mixture crystallization by numerically solving the heat equation on a fine …

White dwarf stars are the most common endpoint of stellar evolution. Therefore, these old,
numerous and compact objects provide valuable information on the late stages of stellar …

We investigate the evolution of magnetic fields generated by the crystallization-driven
dynamo in carbon-oxygen white dwarfs (WDs) with masses $\lesssim1. 05\M_ {\odot} $. We …

The origin of magnetic white dwarfs has been a long standing puzzle. Proposed origin
mechanisms have included: fossil fields frozen in from the progenitor convective core; a …
