Most astronomers accept the binary spin-up scenario for creating millisecond pulsars because they have observed neutron stars speeding up in X-ray binary systems, and almost all radio millisecond pulsars are observed to be in binary systems.

• 多数天文家接受这个假想的模式，因为他们已经在X射线双星系统中观测到了中子星的加速现象，而且几乎所有的毫秒脉冲星都被发现时处于双星系统中。
