Abstract:
Observations of nearby star-forming regions with the Herschel Space
Observatory complement our view of the protoplanetary disks in
Ophiuchus with information about the outer disks.
The main goal of this project is to provide new far-infrared fluxes
for the known disks in the core region of Ophiuchus and to identify
potential transitional disks using data from Herschel.
We obtained PACS and SPIRE photometry of previously spectroscopically
confirmed young stellar objects (YSO) in the region and analysed their
spectral energy distributions.
Description:
The objective of this work is to determine the nature of the sources
detected in the maps produced with PACS and SPIRE observations and to
obtain fluxes in the mid- to far-IR regions when detected.
We had 49 successfully detected sources in at least one PACS band, and
19 in a SPIRE band; PACS also detected all of these.
