| Abstract: | Some statistical studies on the nearby early-type stars proposed for observations by HIPPARCOS are presented. Results on spatial orientation and kinematics are in agreement with those found in the literature. An age estimate based on non-kinematical hypothesis is found to be somewhat smaller than expansion ages derives by some authors.Finally, it is suggested that Gould's Belt may have formed as a result of high-velocity cloud impact on the galactic disk, and some estimations are presented. |
