We also don't know whether these planets started out as part of solar systems,
then were ejected by gravity assisting near collisions with other planets, or
from other nearby stars, if stars there are very close together. I would imagine
that since stars start out as self perpetuating gravity wells of ever increasing
concentrations of gas, that if one such passed too close to another while early
in its formation, and flung it out of the nebula before too much mass could
accrete, then such super jovian planets could form from such a process as well.
