Abstract:
We present CCD BVIKC photometry in the field of the open cluster NGC 2587. We developed a new method to clean statistically the colour-magnitude diagrams. NGC 2587 is found to be slightly younger than the Hyades and probably of solar metallicity. From 18 probable members with measured proper motions, we derived the following mean cluster values: μα = -4.3 ± 3.6 mas yr-1 and μδ = -2.5 ± 3.4 mas yr -1. Colour excesses, E(B - V) = 0.10 and E(V - I) = 0.15 mag, and a heliocentric distance of 3.7 ± 0.7 kpc are obtained. The interstellar extinction in the cluster direction is found to follow the normal reddening law. © International Astronomical Union 2010.
