Kinematics of Vega-like stars

Abstract

We have studied the kinematics of Vega-like stars in the solar neighbourhood. Space velocities are computed for 80 Vega-like stars. We analyse the space velocities of these stars in connection with the young stellar associations and star forming regions in the solar neighbourhood. Our preliminary analysis suggests that many of the Vega-like stars are kinematically connected with the members of the above mentioned associations and star forming regions. This would place a strong constraint on the ages of Vega-like stars which are generally believed to be an older population. Details of the analysis and preliminary results are presented.
