Abstract:
Two fields near the Galactic Center, containing the Quintuplet and Object #17
star-clusters, have been imaged with the ISOCAM circular variable filters
(CVFs) in the wavelength range of 2.47 - 3.08
m and 3.99 - 9.09
m.
Emission of [Ar II] 6.99
m is detected in the ``pistol-shaped'' H II
region (G0.15-0.05) to the south of the Quintuplet cluster.
Absorption probably due to O-H stretching vibration (2.8
m)
is evident in the Quintuplet spectra.
In addition, Quintuplet members and the central part of Object #17 have
CO(4.3
m) and CO (4.7
m) absorption.
Abundant CO might be present in these lines of sight.
