These rare systems — only a few tens were known until recently — were thought to have had their outer coats of stars ripped away by the gravity of other, larger galaxies as they passed nearby, a theory supported by the fact that they were usually found in the centers of large clusters of galaxies.

They form when a large galaxy's gravity pulls one edge of a nearby satellite galaxy more strongly than the other edge, unraveling the galaxy and leaving stars behind.
