Hot Jupiters with a Memory of Their Past

How did hot Jupiters end up orbiting so close to their stars, thus earning their moniker? This is what a recent study published in The Astronomical Journal hopes to address as a team of researchers from The University of Tokyo investigated the orbital evolution of hot Jupiters ended, specifically regarding where their orbits started before orbiting so close to their stars. This study has the potential to help scientists better understand the formation and evolution of exoplanets and what this could mean for finding life beyond Earth.
