Want to find planets? Track the lithium

Abstract:A spectrographic survey has found that stars with planets – like our Sun – tend to have a lot less lithium in their make-up than comparable stars without planetary systems. It is not yet clear how this comes about, but it points the way to a shortcut to finding new exoplanetary systems.
