Absolute proper motion of the galactic open cluster M 67.

Abstract (from CDS):

We derived the absolute proper motion (PM) of the old, solar-metallicity Galactic open cluster M 67 using observations collected with CFHT (1997) and with LBT (2007). About 50 galaxies with relatively sharp nuclei allow us to determine the absolute PM of the cluster. We find (µαcosδ,µδ)J2000.0=(-9.6±1.1,-3.7±0.8)mas/yr. By adopting a line-of-sight velocity of 33.78 ±0.18km/s, and assuming a distance of 815±50pc, we explore the influence of the Galactic potential, with and without the bar and/or spiral arms, on the galactic orbit of the cluster.
