Study of dynamical status of the globular cluster NGC 1851 using ultraviolet imaging telescope

We present the study of dynamical status globular cluster NGC 1851. A combination multiwavelength space and ground-based data sets are used for analysis. In order to select genuine members, we astro-photometric available from HST GAIA-DR2 catalogs. The BSS radial distribution is plotted center outskirts. shows a central peak, followed by dip at intermediate radii (rmin ~ 90'') rising trend in also estimated A+rh parameter as 0.391 +/- 0.006 validate findings study. On basis minima value parameter, conclude that 1851 belongs Family II classification an state cluster.
