P-Pdot diagram

(diagram comparing the rotation and the slowing of pulsars)

A P-Pdot diagram is a graph plotting the rotation periods of pulsars with the rate of change in their periods, aiming to reveal patterns that make evident the characteristics and evolution of pulsars.

The diagrams tend to show a difference between binary pulsars and lone pulsars, where the binary pulsars have a shorter period and are slower to slow down.
