This Earth-Sized Star Rotates Once Every 25 Seconds - Gizmodo
Astronomers announced this week the discovery of the fastest-rotating white dwarf star on record, with a spin rate of once every 25 seconds.
The star is about the size of Earth but, by the team’s measurements, contains least 200,000 times more mass, making the dense little object a spinning freak of nature.
That act makes J0240+1952 the second-ever discovered star that acts as a magnetic propeller, according to the team?From the original magnetic propeller star, researchers expected that the systems needed to have a fast-spinning star, and J0240+1952 adds some particularly extreme evidence for that hypothesis
Can you imagine if an Earth day was 25 seconds, day and night cycling rapidly across the sky
