JHK photometry in Cluster [BDS2003] 107
Listed in IVOA Registry (Virtual Observatory)
We present new near-infrared classification spectra for nine candidate members of the galactic cluster [BDS2003] 107 (Cluster 107) observed with the IRTF SpeX instrument.
Description
We can spectroscopically classify at least three members, two of which have published 2MASS photometry. These two stars provide preliminary values for the approximate age (10^6^yr), distance (<=2kpc), and extinction (A_V_~23) of the young cluster.
Based on the properties of the brightest members we have identified, on the surface Cluster 107 appears to be very similar to the well-studied Orion cluster. We find a single mid-O dwarf star and a number of early-B stars, along with massive young stellar objects (YSOs) in the field. The massive YSO Star 63 shows simultaneously an early-B spectral classification in the short K-band with CO band-head emission at 2.3um.

This massive YSO looks similar to other luminous CO emission objects seen in young, massive clusters through out the Galaxy and provides additional evidence for the existence of circumstellar disks around even fairly massive stars. Several previously identified radio sources, presumably associated with very early star formation, lie within this field, three of which appear to have near-infrared counterparts as detected in images we obtained with the SpeX acquisition camera.
