Search for young sub-stellar objects in the Chamaeleon II cloud using wide-field imaging techniques .
2006
We present preliminary results on the selection of low-mass Pre-Main Sequence (PMS) stars and young Brown Dwarf (BD) candidates in the Chamaeleon II dark cloud using wide-field imaging techniques. We aim to study the Initial Mass Function (IMF) of Chamaeleon II in the very low-mass and sub-stellar regimes. The PMS and BD candidates were selected on the basis of color-magnitude diagrams (CMDs) and theoretical isochrones. We can also roughly estimate the effective temperature of the DB candidates and study the level of Hα emission of the candidates.
