The rotational vector of the Local Stellar System
It is shown that the rotational vector of nearby stars derived from the proper motions of the Hipparcos catalogue is not perpendicular to the Galactic plane. We found that the rotation of stars nearer than 150 pc can be considered as the superposition of the Galactic rotation and the Local Stellar System rotation. The kinematics of stars which are more distant than 200 pc are very close to the standard model of the Galactic rotation.
