  A sample of 46 stars, host of exoplanets, is used to search for a connection
between their formation process and the formation of the planets rotating
around them. Separating our sample in two, stars hosting high-mass exoplanets
(HMEs) and low-mass exoplanets (LMEs), we found the former to be more massive
and to rotate faster than the latter. We also found the HMEs to have higher
orbital angular momentum than the LMEs and to have lost more angular momentum
through migration. These results are consistent with the view that the more
massive the star and higher its rotation, the more massive was its
protoplanetarys disk and rotation, and the more efficient the extraction of
angular momentum from the planets.
