J/A+A/471/499   Low-mass stars and brown dwarfs in Blanco 1      (Moraux+, 2007)

The lower mass function of the young open cluster Blanco 1: from 30M{Jup} to 3M. Moraux E., Bouvier J., Stauffer J.R., Barrado y Navascues D., Cuillandre J.C. <Astron. Astrophys. 471, 499 (2007)> =2007A&A...471..499M
ADC_Keywords: Clusters, open ; Stars, dwarfs ; Photometry, infrared Keywords: stars: low-mass, brown dwarfs - stars: mass function - open clusters and associations: individual: Blanco 1 Abstract: We performed a deep wide field optical survey of the young (∼100-150Myr) open cluster Blanco 1 to study its low mass population well down into the brown dwarf regime and estimate its mass function over the whole cluster mass range. Description: From a CFHT optical survey of the young open cluster Blanco 1, we identified low mass star and brown dwarf candidate cluster members. For each candidate, the photometric parameters and J2000 coordinates are given. File Summary:
