Abstract
Luminosity profiles and dynamical parameters of 12 globular clusters in the Large Magellanic Cloud (SB(s)m) are obtained from the concentric aperture photoelectric photometry of 3 different aged clusters and the collected photometric data of 9 clusters. The total masses of the globular clusters are the calculated using the equation M⨀ = Mrtj(4Q^2-k^2), which is derived from the theoretical rotation curve for the exponential disk (Chun 1987). These masses lie between 0.3 x 10^4 and 15.8 x 10^4 M⨀ . From the determined total mass and luminosity ratios are also derived. The M/L ratio of a cluster increases with the cluster age; about 0.03 for the youngest clusters (SWB I) and about 0.24 for the oldest clusters (SUB VII). There is a difference in M/L by a factor of 10 between the galactic globular clusters and the old globular clusters in the LCM.
