Brown dwarf candidates in the Serpens cloud core

The Serpens cloud core is populated by a young, low-mass stellar cluster with members in many different evolutionary stages. We revisit the near-IR properties of the cluster in this contribution. A total of 188 near-IR sources are identified, including new members suggested in this work. Near-IR colour-magnitude and colour-colour diagrams allow us to suggest 42 objects among the cluster members as brown dwarf candidates. A considerable fraction of them present near-IR excesses which indicates that many of these very low mass objects are still surrounded by prominent dust accretion disks.
