What Is the Origin of Millisecond Pulsars

question 102

Multiple Choice

What is the origin of millisecond pulsars?

• A) As a pulsar cools, it collapses further. This causes its rotation rate to increase.
• B) Pulsars in binary systems can draw mass from the binary companion. This mass, impacting the pulsar's surface, causes its rotation rate to increase.
• C) The jets that radiate energy away from a pulsar cause it to become smaller and to rotate faster.
• D) The rotation period for most pulsars is actually less than a millisecond. So, the natural slowing as it loses energy moves it into the millisecond range.
