Astronomy - If you were to inject a star's core with a piece of iron, would it die?

After watching how the universe works episode on extreme stars a question popped into my head. Can a form of life kill a star?

Lets say a civilization found a way to get a "care package" to the centre of a star with say a missile, and that package was filled with iron. Would the star suddenly die or would it reject the iron and not try to fuse it?

Iron doesn't kill stars, it's just that stars cannot use iron as fuel because the fusion of iron doesn't release energy. When iron accumulates in the core of a star, it means that the star has run out of fuel.

It's a similar relation to ashes and a fire. Ashes aren't what kill a fire.
