NGC 1912 and NGC 1907: A close encounter between open clusters?

DE OLIVEIRA M.R., FAUSTI A., BICA E. and DOTTORI H.

Abstract (from CDS):

The possible physical relation between the closely projected open clusters NGC 1912 (M 38) and NGC 1907 is investigated. Previous studies suggested a physical pair based on similar distances, and the present study explores in more detail the possible interaction. Spatial velocities are derived from available radial velocities and proper motions, and the past orbital motions of the clusters are retrieved in a Galactic potential model. Detailed N-body simulations of their approach suggest that the clusters were born in different regions of the Galaxy and presently experience a fly-by.
