Pulsar JO437-4715


I find it outrageous that pulsar JO437-4715 rotates at 173.7Hz.

This is a star almost twice as massive as our sun, whipping itself around, a full rotation every 5.75ms.

What’s the fastest you can spin yourself round? I’m guessing it’s a lot less than 174Hz and you’re considerably smaller than JO437-4715.

I dunno. Astrophysics is more fantastic than most fiction I read.

@protozoaradio? – this baby is apparently accurate enough to be used as a clock, it’s accurate to one part in 1015
