Millisecond pulsars Max-Planck-Gesellschaft - The discovery of deceleration
Today we know of about 200 such pulsars with spin periods between 1.4 to 10 milliseconds.
“The result is that the millisecond pulsars loose about half of their rotational energy in the so-called Roche-lobe decoupling phase.”
