The inert remnants have enough mass to force protons and electrons together into neutrons (K-electron capture), producing a neutron star.
... and occasionally, my personal horror of horrors, a magnetar

https://en.m.wikipedia.org/wiki/Magnetar

...The magnetic field of a magnetar would be lethal even at a distance of 1,000 km due to the strong magnetic field distorting the electron clouds of the subject's constituent atoms, rendering the chemistry of known lifeforms impossible.

Would it stick to a giant refrigerator door?

The Sun's protostar mass was in a narrow range which allowed for a T-Tauri class event. Our Sun is in a moderately stable second stage after its short life as a protostar. Fusion followed by a massive explosion of matter produced the protoplanetary disk containing all of the elements heavier than iron. The accretion of the disk over time produced the planets and other system solar matter in its present form. The sun will slowly cool and expand over a billion+ years until engulfs the inner plants as a red giant. A few more billion years of radiating its energy, the sun will collapse and cool into a dark carbon sphere. We can observe the evolution of similar stars in various phases in our galaxy, and it's quite common but doesn't account the majority of matter in the universe.

At least that's how I remember the basics as taught in the Planetary Geology class I took many moons ago.

Reminds me of Thing Explainer from Randall Munroe. "Could you touch a neutron star"
