I What happens to the material not involved in the core collapse of a supernova?

TL;DR Summary

Supernovas

What happens to the material not involved in the core collapse of a supernova? This would be the outer portion of a star or any cloud that surrounds the star. All material to infinity or does some material remain close -- gravitationally close that might collapse if it could. thanks

Have you looked at supernova remnants on the net ? there's lots of them

Here's a couple of random examples
M1 - Crab Nebula in Taurus
The Crab Nebula is around 10 lightyears across and continues to expand at around 4.8 million km/h

N1006

I know nothing, but I googled:
Massive stars in a certain mass range may form low-mass black holes after supernova explosions. In such massive stars, fallback of ~0.1 M☉ materials onto a black hole is expected because of a deep gravitational potential or a reverse shock propagating back from the outer composition interface.

supernova remnant...duh!
https://en.wikipedia.org/wiki/SN_1987A looks more controlled...like a smoke ring
thanks
