A new method for exploring the physics of white dwarf stars

Grab a mixing bowl from your kitchen, throw in a handful of aluminum balls, apply some high voltage, and watch an elegant dance unfold where particles re-arrange themselves into a distinct “crystal” pattern. This curious behavior belongs to the phenomenon known as Wigner crystallization, where particles with the same electrical charge repel one another to … Read more

Fastest eclipsing binary, a valuable target for gravitational wave studies

Observations made with a new instrument developed for use at the 2.1-meter (84-inch) telescope at the National Science Foundation’s Kitt Peak National Observatory have led to the discovery of the fastest eclipsing white dwarf binary yet known. Clocking in with an orbital period of only 6.91 minutes, the rapidly orbiting stars are expected to be … Read more
