  We report on the Herschel Gould Belt survey (HGBS) of ChaII, focusing on the
detection of Class I to III young stellar objects (YSOs). We aim at
characterizing the circumstellar material around these YSOs and understanding
which disk parameters are most likely constrained by the new HGBS data. We
recovered 29 out of the 63 known YSOs in ChaII with a detection in at least one
of the PACS/SPIRE pass-bands: 3 Class I YSOs (i.e.,100%), 1 Flat source (i.e.,
50%), 21 Class II objects (i.e., 55%), 3 Class III objects (i.e, 16%) and the
unclassified source IRAS 12522-7640. We explore PACS/SPIRE colors of this
sample and present modeling of their SEDs using the RADMC-2D radiative transfer
code. We find that YSO colors are confined in specific regions of PACS/SPIRE
color-color diagrams. These color ranges are expected to be only marginally
contaminated by extragalactic sources and field stars and, hence, provide a
useful YSO selection tool when applied altogether. We were able to model the
SED of 26 out of the 29 detected YSOs. We discuss the degeneracy/limitations of
our SED fitting results and adopt the Bayesian method to estimate the
probability of different values for the derived disk parameters. The Cha II
YSOs present typical disk inner radii around 0.1 AU. The lower limit to Rc is
typically around 50 AU. The lower limits to Mdisk are proportional to the
stellar masses with a typical 0.3% ratio, i.e., in the range estimated in the
literature for young Class II stars and brown dwarfs across a broad range of
stellar masses. The estimated flaring angles, although very uncertain, point
towards rather flat disks (1+phi less than 1.2), as found for low-mass M-type
YSO samples in other star forming regions. Thus, our results support the idea
that disk properties show a dependence on stellar properties.
