Kronberger 49: a new low-mass globular cluster or an unprecedented bulge window?
ORTOLANI S., BONATTO C., BICA E., BARBUY B. and SAITO R.K.
Abstract (from CDS):
We employ optical and near-infrared photometry to study the stars in the direction of the star cluster candidate Kronberger 49. The optical color-magnitude diagrams (V, I, and Gunn z photometry obtained with the Galileo Telescope) are tight and present evidence of a main-sequence turnoff. We may be dealing with a low-mass, metal-rich globular cluster located in the bulge at a distance from the Sun of d☉= 8±1 kpc. Alternatively, it may be a dust hole through which we are sampling the bulge stellar population affected by a very low amount of differential reddening.
