Abstract The Laser Interferometer Space Antenna (LISA) will be a transformative experiment
for gravitational wave astronomy, and, as such, it will offer unique opportunities to address …

In this paper we review the current status of research on the observational and theoretical
characteristics of isolated and binary magnetic white dwarfs (MWDs). Magnetic fields of …

Astronomers have discovered thousands of planets outside the Solar System, most of which
orbit stars that will eventually evolve into red giants and then into white dwarfs. During the …

We present a catalogue of white dwarf candidates selected from the second data release of
Gaia (DR2). We used a sample of spectroscopically confirmed white dwarfs from the Sloan …

Context. Heavy metals in the atmospheres of white dwarfs are thought in many cases to be
accreted from a circumstellar debris disk, which was formed by the tidal disruption of a rocky …

The detection of a dust disk around the white dwarf star G29-38 and transits from debris
orbiting the white dwarf WD 1145+ 017 (ref.) confirmed that the photospheric trace metals …

Circumstellar disks of planetary debris are now known or suspected to closely orbit
hundreds of white dwarf stars. To date, both data and theory support disks that are entirely …

The fates of planetary systems provide unassailable insights into their formation and
represent rich cross-disciplinary dynamical laboratories. Mounting observations of post-main …

Many white dwarf stars show signs of having accreted smaller bodies, implying that they
may host planetary systems. A small number of these systems contain gaseous debris discs …

Evidence is now compelling that elements heavier than helium in many white dwarf
atmospheres have accumulated by accretion from orbiting rocky bodies, often larger than …
