Observational constraints on companions inside of 10 AU in the HR 8799 planetary system

Hinkley, Sasha; Carpenter, J M; Kraus, Adam L; Ireland, Michael


We report the results of Keck L′-band non-redundant aperture masking of HR 8799, a system with four confirmed planetary mass companions at projected orbital separations of 14-68 AU. We use these observations to place constraints on the presence of plane
