Sketch of the model geometry for a binary with a common envelope (in the left panel) and the orientation consistent with the G2/DSO nominal trajectory on the sky (in the right panel). The two components (i.e., hot star+neutron star in this example) deviate from each other, the first one being bound and the other one unbound at the moment of pericentre passage. The cloud is then dispersed in the ambient medium and eventually accreted onto the SMBH.
