A star in a spin

Post by brian livesey »

A white dwarf has been discovered that has a rotational spin of 25 seconds. This makes the star the fastest of its type so far discovered. The high rotational spin is due to what astrophysicists call a magnetic propellor system, a phenomenon that’s extremely rare.
The white dwarf is sloughing off material from its companion star and hurtling it into space at around 3,000km per second. Researchers say that the magnetic propellor white dwarf is only the second one to have been discovered in more than 70 years. The research was published in the Monthly Notices of the Royal Astronomical Society: Letters.
