SUMMARY:New Indicators of star cluster dynamical evolution
DESCRIPTION:New Indicators of star cluster dynamical evolution\nDrs. Bhavan
 a Purohith Bhaskar Bhat\n\nGlobular clusters (GCs) are one of the oldest s
 tellar systems where individual stars could be resolved and are essentiall
 y the fossils of galaxy formation. Understanding their internal evolution 
 is crucial for formation and evolution of the host galaxies as well as, to
  interpret their present-day structural and kinematical properties. The dy
 namical evolution of these collisional systems is significantly affected b
 y properties such as binary fraction, concentration, tidal field of the ga
 laxies and so forth. As a result, GCs with the same chronological age can 
 be in very different dynamical evolutionary stages, making the determinati
 on of their "dynamical age" observationally challenging. \nIn this ta
 lk, I will be presenting new empirical parameters measurable from observat
 ions which are able to trace the different phases of dynamical evolution o
 f star clusters. I will also discuss the impact of heating sources such as
 , primordial binaries and stellar mass blackholes on the dynamical evoluti
 on and in-turn on the new empirical parameters.\n
