How do we determine what's in the core of stars/planets?

    I tried searching but I must've done something wrong, so...

    How do we determine what material is at the core of a planet? Do certain metals emit something we can detect?

    I really don't know how to phrase this in an intelligent way, so please bear with me. :biggrin:

    So that's how they do it! I never thought of that. Nice abstract though, but I can't get to the full version.
