Illustration of the origin of magnetic fields in white dwarfs in close binaries (to be read counter clockwise). The magnetic field appears when a crystallizing white dwarf accretes from a companion star and as a consequence starts to spin rapidly. When the white dwarfs field connects with the field of […]

ANIMATION Physicists on the hunt for a rarely seen magnetic spin texture have discovered another object that bears its hallmarks, hidden in the structure of ultra-thin magnetic films, that they have called an incommensurate spin crystal. University of Warwick physicists set out to find Skyrmions, only to find near-identical object with […]

Remnants of planetary crust disintegrating under the tidal forces around a cool white dwarf. Material in the disc becomes vapourised close to the central star and flows onto the white dwarf atmosphere. Credit: University of Warwick/Mark Garlick Remnants of planets with Earth-like crusts have been discovered in the atmospheres of […]

Left: Oppositely charged magnetic bands, represented in red and blue, march toward the equator over a 22-year period. When they meet at the equator, they annihilate one another. Right: The top animation shows the total sunspot number (black) and the contributions from the north (red) and south (blue) hemispheres. The […]
