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.
