The distribution of relative proper motions of wide binaries in Gaia DR2: MOND or multiplicity?
We examine the distribution of on-sky relative velocities for wide binaries previously assembled from theGaia DR2 data and focus on the origin of the high-velocity tail of apparently unbound systems, which may be interpreted as evidence for non-Newtonian gravity in the weak field limit. We argue tha...
