Abstract: We performed a deep wide field optical survey of the young (~ 100 - 150 Myr) open cluster Blanco1 to study its low mass population well down into the brown dwarf regime and estimate its mass function over the whole cluster mass range.The survey covers 2.3 square degrees in the I and z - bands down to I ~ z ~ 24 with the CFH12K camera.

The models include a new wind braking law based on recent numerical simulations of magnetized stellar winds and specific dynamo and mass - loss prescriptions a... ▽ More We present new models for the rotational evolution of solar - like stars between 1 Myr and 10 Gyr with the aim to reproduce the distributions of rotational periods observed for star forming regions and young open clusters within this age range.

Considering two different cluster ages (100 and 150 Myr), we selec... ▽ More We performed a deep wide field optical survey of the young (~ 100 - 150 Myr) open cluster Blanco1 to study its low mass population well down into the brown dwarf regime and estimate its mass function over the whole cluster mass range.The survey covers 2.3 square degrees in the I and z - bands down to I ~ z ~ 24 with the CFH12K camera.
