Abstract:
We present near infrared (J, H and Ks) observations of a 5'x10' sample
field in the Serpens Star Formation region obtained with SOFI at the
NTT. These observations are sensitive enough to detect a 20MJup
brown dwarf through an extinction of AV∼16 and are used to build an
infrared census of this field in the cluster. From photometry and
mass-luminosity models, we have developed a detailed methodology to
extract quantitative parameters (distance modulus, extinction,
spectral type, masses) for objects observed towards and inside the
Serpens molecular cloud. An extinction map of the region is derived
allowing us to disentangle cloud members from background field
objects. Luminosities and masses for 14 low-mass stars and substellar
object candidate members of the cluster are derived.
