What conclusion might scientists draw if a strong remnant like Tycho's lacks a detectable pulsar?
Answer
The core collapse resulted in a black hole or the neutron star received a kick that ejected it from view
The absence of a visible pulsar in some strong remnants suggests the central object is either a black hole, which provides no bright electromagnetic source, or the neutron star received a significant recoil kick causing it to leave the remnant structure.
