Title: Deep optical & IR imaging of Musca

Abstract: We propose to carry out a deep optical and NIR survey of the Musca cloud to study its population of young stars. This star forming cloud is part of the Chamaeleon-Musca complex, a region with a rich population of pre-main sequence (PMS) stars. The Chamaeleon-Musca complex is a target of both the Spitzer Legacy Survey and Herschel Key Programme of the Gould Belt clouds, and deep optical/near-IR data will complement these space-based observations, revealing the population of young low- mass stars and brown dwarfs. Previous studies of the Chamaeleon clouds have demonstrated the power of wide field optical and near-IR imaging in revealing the population of young low-mass stars and brown dwarfs. For the Musca cloud such a basic optical/near-IR survey is still lacking despite the fact that this close-by cloud seem to have a much richer population of young stars than previously anticipated. Our study provides fundamental stellar parameters allowing comparison studies to the PMS populations in the different Chamaeleon-Musca clouds. Ultimately the sample increases the number of stars in the Chamaeleon- Musca complex, allowing for a statistically meaningful estimate of the IMF in the region.
