Context. Though only a handful of extrasolar planets have been discovered via direct imaging, each of these discoveries had tremendous impact on our understanding of planetary formation, stellar formation and cool atmosphere physics. Aims. Since many of these newly imaged giant planets orbit massive A or even B stars we investigated whether giant planets could be found orbiting low-mass stars at large separations. Methods. We have been conducting an adaptive optic imaging survey to search for planetary-mass companions of young M dwarfs of the solar neigbourhood, to probe different initial conditions of planetary formation. Results. We report here the direct imaging discovery of 2MASS J01033563-5515561(AB)b, a 12-14 MJup companion at a projected separation of 84 AU from a pair of young late M stars, with which it shares proper motion. We also detected a Keplerian-compatible orbital motion. Conclusions. This young L-type object at planet/brown dwarf mass boundary is the ?first ever imaged around a binary system at a separation compatible with formation in a disc.

Quite a difficult one to figure out in terms of both mass ratio and separation:

In any case, the discovery of 2MASS0103(AB)b brings most current stellar and planetary formation theories to their limits while others, such as core-accretion, can probably be excluded. The very existence of such a peculiar system therefore provides a very valuable test case against which current and future stellar and planetary formation theoretical models can be tested.

Has every planet with two stars to be dubbed as "Tatooine", even if it has nothing to do with that fictional world in terms of orbital parameters and planetary mass?

Sure, same as popular science articles can't mention a particular Saturnian satellite without also bringing up a certain fictional space station, and some wit saying "that's no moon" in the comment threads.

Indications that the planetary-mass object is accreting:

Based on the discoverer designation of the system in the WDS catalogue (DLR 1) they refer to the system as "Delorme 1", making the companion Delorme 1 (AB)b, which is somewhat easier to handle than the 2MASS identifier.
