Infrared images and photometry of the cluster near G 0.15-0.05.
Abstract
An unusual infrared cluster, first identified as a triplet of bright sources and later as a quintuplet, has been found near galactic coordinates l = 0.15 deg, b = 0.05 deg on images obtained with the ESO infrared array camera. The JHKL (1.2 to 3.4 microns) colors of several of the individual sources within the cluster are unusually red, leading them to be associated with a number of similar objects which are identified with luminous IRAS point sources near the Galactic Centre. It is suggested that they are recently formed early-type stars embedded in dust shells.
