Giant hot planets forming around small stars may explain the prevalence of the so-called "hot Jupiters" which seem to make up an inordinate amount of the exoplanets we have detected so far. The fact that the authors were able to examine the phenomenon vis-a-vis a computer simulation is pretty exciting.

I would argue the apparent abundance of 'Hot Jupiter's' is more of an 'Observer Effect' than an actuality - large planets orbiting close to their suns are easier to detect by far than worlds further out.

That said, in connection with my other project, I looked at multiple star systems. Binary systems composed of M dwarfs appear to be fairly common.

True, however observer bias and greater prevalence are not mutually exclusive.
