"Star-Hopper" is the name given to a planet that moves from one binary star to its twin, either by collision or other means.  It's an unfortunate term in that "Star-Hopping" is also used to describe the nocturnal behavior of amateur star-gazers.

The major study to date on Star-Hoppers (the planetary kind) was done several years ago by Kaitlin M. Kratter at the Harvard-Smithsonian Center for Astrophysics.

Her research indicates that planets are more likely to change orbits from one binary to another when there is a large size difference between the twin stars.  Her research and paper on star-hopping concentrated on older star systems, however the same principle would seem to apply to a younger binary pair in which one was a larger star (like our sun) and the twin was a smaller star (such as a Red or Brown Dwarf).

Dr. Kratter since "changed her orbit" to the University of Colorado where she hosted a lecture on binary star and associated planet simulation:

Subsequent to this, she has "hopped over" to the University of Arizona:
