Fundamental parameters of isolated galaxy triplets in the local
  Universe: Statistical study
  Understanding the dynamics of galaxy triplet systems is one of the
significant ways of obtaining insight into the dynamics of large galaxy
clusters. Toward that aim, we present a detailed study of all isolated triplet
systems (total of 315) taken from the `SDSS-based catalogue of Isolated
Triplets' (SIT). In addition, we compared our results with those obtained for a
sample of triplets from the Local Supercluster (LS), SDSS-triplets, Tully's
catalogue, Wide (W) and Compact (K)-triplets. In addition, we performed the
correlation between the dynamical parameters and the Large Scale Structure
(LSS). Interestingly, we found that there is no correlation between both the
mean projected separation for the triplet systems and the LSS and its dynamical
parameters. Furthermore, we found that only 3 percent of these systems can be
considered as compact since the mean harmonic separation (rh) is more than 0.4
Mpc for 97 percent of the population.Thus we may conclude that, mergers might
not have played a dominant role in their evolution.
