If some stars that are lightyears away are dead, does that mean the exoplanets we find are also dead?

Question

I get really excited over exoplanets that are Earth-like so I’m wondering how this works.

Answer 1

Define “dead.”

Stars don’t really die. They change form. Sometimes they explode, but then might form into new stars billions of years later.

The planets around them may or may not still be there.

If you mean dead as in can’t support life, that’s most exoplanets already. But when a star changes or explodes, it won’t be more productive for life, so that would make the planet “deader.”
