TESTING the BINARY TRIGGER HYPOTHESIS in FUors

Green, Joel D.; Kraus, A L; Rizzuto, Aaron C.; Dupuy, Trent; Mann, Andrew W; Kuruwita, Rajika; Ireland, Michael

Description

We present observations of three FU Orionis objects (hereafter, FUors) with nonredundant aperture-mask interferometry at 1.59 μm and 2.12 μm that probe for binary companions on the scale of the protoplanetary disk that feeds their accretion outbursts. We do not identify any companions to V1515 Cyg or HBC 722, but we do resolve a close binary companion to V1057 Cyg that is at the diffraction limit ($\rho =58.3\pm 1.4$ mas or 30 ± 5 au) and currently much fainter than the outbursting star...[Show more]
