Main image: θ1 Ori B group imaged in H-band. B1 is an eclipsing binary B1, 5. It was created with NaCo data, based on data obtained from the ESO Science Archive Facility under request number 342335, ESO program 60.A-9800(J). Additionally, with GRAVITY we detected another companion B6 at a separation of ∼13 mas, shown in the zoomed image of B1, 5, 6 (K-band). The image of B6 orbiting B1, 5 is reconstructed from our observations. The zoom into the spectroscopic binary B1, 5 is only a representative image and was not created with observational data.
