SUMMARY:Optical and infrared studies of Galactic open clusters
DESCRIPTION:Optical and infrared studies of Galactic open clusters\nDr. Han
 s Zinnecker\n\nIn the first (optical) part, we present our recent results 
 on mass and luminosity function of Galactic open clusters, a new statistic
 al study based on the ASCC-2.5 catalogue of bright stars, complete to abou
 t 1 kpc around the Sun. This includes a new determination of the fraction 
 of field stars born in open clusters. It also briefly addresses the issue 
 whether all massive stars are exclusively born in clusters.\n\nIn the seco
 nd (infrared) part, we discuss the prospects of a 42m European ELT to "see
 " the origin of massive stars in dense embedded protoclusters, by penetrat
 ing dense proto- cluster clouds up to 200 mag of visual extinction at 2-5 
 microns. High-angular resolution AO imaging as well as 3D integral field s
 pectroscopy are required to study the stellar density, binary content, and
  dynamical properties of these highly obscured, massive, compact star clus
 ters.\n\n
