New runaway OB stars with HIPPARCOS

New runaway OB stars with HIPPARCOS

A Monte Carlo method for detection of runaway OB stars from observational data is proposed. 61 runaway OB star candidates have been detected by an analysis of Hipparcos proper motions. The peculiar tangential and total transverse velocities have been determined for these stars. A list of the detecte...

Zusammenfassung:A Monte Carlo method for detection of runaway OB stars from observational data is proposed. 61 runaway OB star candidates have been detected by an analysis of Hipparcos proper motions. The peculiar tangential and total transverse velocities have been determined for these stars. A list of the detected runaway star candidates is presented. The evidence of a discrepancy between photometric and parallactic distances of runaway OB star candidates is presented.
