Summary
The powerhouse of black widow binaries are pulsars — rapidly spinning neutron stars which are the collapsed cores of now dead massive stars. Normally pulsars die down, but can become re-energised when they pick up smaller stars which stray too close to the pulsar’s immense gravitational pull. The “recycled” pulsar gets new life, destroying the smaller star in the process.
On neutron stars, and trying to be better.
