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 …

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 …

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 …

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 …

We present a census of photometrically detected rotation periods for white dwarf (WD) stars.
We analyzed the light curves of 9285 WD stars observed by the Transiting Exoplanet Survey …

Recent determinations of the total rate of the 12 C+ 12 C nuclear reaction show non-
negligible differences with the reference reaction rate commonly used in previous stellar …

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 …
