SONYC - short for Substellar Objects in Nearby Young Clusters - is a long-term project to study the frequency and properties of brown dwarfs in star forming regions. SONYC was initiated in 2006 and is carried out in collaboration between Aleks Scholz (DIAS), Ray Jayawardhana (University of Toronto), Koraljka Muzic (ESO Santiago), Vincent Geers (DIAS), and Motohide Tamura (NAOJ). As of 2012, we have published results for three regions, NGC1333, Chamaeleon-I, and Rho Ophiuchus. This page serves as a data repository for SONYC. We provide links to the most important catalogues and to the spectra of the confirmed very low mass objects in our target regions.
