Direct Imaging Detection of Low-Mass Companions Orbiting Giant Stars and Binaries Justin Crepp, Caltech High-contrast imaging is a rapidly maturing field. Observations now achieve sensitivities that are sufficient to complement the discoveries made with the Doppler radial velocity method and others. In the near future, technology developments in adaptive optics and coronagraphy will further enhance our understanding of planet formation and evolution. Like the other techniques, direct imaging observations will eventually explore as large of a parameter space as possible, including stellar mass and multiplicity. In this talk, I will discuss the prospects and motivation for targeting large angular diameter stars and close-separation binaries from the ground and space.
