Millisecond pulsars, their evolution and applications

RN Manchester - Journal of Astrophysics and Astronomy, 2017 - Springer
Millisecond pulsars (MSPs) are short-period pulsars that are distinguished from “normal”
pulsars, not only by their short period, but also by their very small spin-down rates and high …
