| dc.description | We carry out a large program to classify newly discovered star clusters from Froebrich et al. (2006) in the inner Galaxy. Here, we present a first analysis of a new high-priority globular cluster candidate, FSR1735 at l=339.1879; b=-1.8534, based on new deep near infrared observations from Sofi at the NTT. A significant peak in the K-band luminosity function is found, which is interpreted as the clump of post-He-flash stars. The distance and the reddening of the cluster are determined to 9.1kpc and A_K=0.5mag, respectively, the metallicity is estimated to [M/H]=-0.8. Radial star density profiles are used to measure the core radius and the tidal radius of the cluster. The lack of signs for on-going star formation and the position in the Galaxy pose strong arguments against the interpretation of this object as a young or old open cluster. All the observational evidence is in agreement with the interpretation that FSR1735 is a so far unknown globular cluster in the inner Galaxy. | |
