Any GURPS stats for black holes, pulsars, etc?

[clu2415]

Do you mean the tidal stresses from the gravity wells? A pulsar’s radiation emission? The radiation emitted by a black hole’s accretion disc?

Neutron stars (including pulsars) have a ridiculous magnetic field strength—and then there’s magnetars which are even higher! There could be an induction hazard from moving a metal object through that field. Neutron stars also have such intense gravity that they bend the light from their far side. You can observe 3/4 of their surface from one side!
