It's the fate of a small star like our sun to end like this, first bloating up into a red giant and then soon thereafter turning into a tiny white dwarf. We see the remains of these recently deceased sun-like stars all around the solar neighborhood.

However, a star that has between 3 and 8 times more mass than the sun takes a very different path toward its end—a very violent path—that does indeed disturb its neighbors.

The squeeze of gravity inside a very massive star is so great, that very high temperatures in the core are reached quickly, and so the fusion rate of hydrogen is very fast.
