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...

When restricting the OC sample to those located in the solar neighbourhood, with the aim of avoiding incompleteness effects, we also find that these clusters are engraved with clear signs of enhanced formation at both ages. © 2010 ESO. 2010 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_00046361_v513_n11_p_Piatti http://hdl.handle.net/20.500.12110/paper_00046361_v513_n11_p_Piatti |
