Understanding the dynamical status of Galactic Globular Cluster NGC 6656
Abstract
We present the study of horizontal branch morphology of the cluster NGC 6656. A blueward shift in temperature of about ~5000 K (nM-jump) in the color-color plot is detected.To explain this feature, we study the presence of stellar-mass black hole by plotting Projected density profile (PDP) in the central HST region. The PDP in the inner region (r < 10″) can be nicely reproduced by the king+BH model. The blue ward shift in temperature can be due the presence of stellar mass black holes in the centre.
