Evidence of enhanced formation episodes in the Galactic open cluster system

Aims.The exciting debate about the existence of signs of enhanced formation of Galactic open clusters (OCs) is revisited here on the basis of a revised age distribution. Methods.The data were taken from the recently updated 2009 version of the Dias et al.'s 1787 OC catalogue. Results.We found t...
