# Pulsars and Angular Momentum

## Main Question or Discussion Point

Hello,

Does the Conservation of Angular Momentum have any relation to the rapid rotation of Pulsars?
I've reasoned that the Angular Momentum of the "parent" star would be concentrated on the smaller pulsar and would produce a greater frequency of rotation.

Thanks,

You are basically correct, but some pulsars are even faster than that. The extra momentum comes from infalling material usually from a companion star. The max seems to be about 700 revolutions per second.
