Pulsational pair-instability supernovae: gravitational collapse, black-hole formation, and beyond — mentioned by pangeorg

Astrophysicist here :) You are correct in some way to say that the star "squeezes" the core. During the evolution of massive stars, say stars roughly 8 times as massive as our sun, the core grows to a point where it just cannot support itself. It collapses and in consequence triggers the type 2 supernova. Another commenter already mentioned correctly that the remnant of the explosion is typically a neutron star or a black hole. The asymmetries seen in the gaseous remnant are caused by the explosion, which typically is highly asymmetric for stars of larger mass…
