And so the Sun resumes its peaceful orbit around the Earth.

Seriously, what the hell was the story's point? You can stop a supernova by rectifying an equation? Or don't worry, it's not going to go supernova 'cos I got an equation o' mine wrong? That doesn't change anything; it's still happening.

If they had a part where they fired a missile at the sun, or planned a space mission, it might have made more sense. And staying underground to escape it? Wrong. Supernovas completely destroy whole solar systems. No one would survive.
