Abstract:
We present the results of a mid-infrared (5-16.5µm) imaging
spectroscopy survey of Young Stellar Objects (YSOs) and their
surrounding environment in four low-mass star formation regions:
R CrA, ρ Ophiuchi, Serpens and Chamaeleon I. This survey was
performed using ISOCAM and its Circular Variable Filters (CVF) and
observed 42 YSO candidates: we were able to obtain complete
5-16.5µm spectra for 40 of these with a spectral resolving power of
λ/Δλ∼40.
Description:
5-16.5µm imaging spectroscopy was performed on six target fields in
four low-mass star formation regions using the ISOCAM-CVF, on various
dates between April 1996 and February 1997.
