A millisecond pulsar (MSP) is a pulsar with a rotation period of around 1-10 milliseconds. They are often detected using radio waves, X-rays or gamma rays. In addition to the interest in the pulsars themselves, they are useful as extremely accurate clocks at considerable distance, in particular, for pulsar timing arrays.
A pulsar that is not an MSP is sometimes referred to as a canonical pulsar (CP).
