Abstract:

 

In this work we have used the Viril theorem to investigate  the dynamical stability of Hickson compact groups of galaxies.  The  average luminous mass of the galaxies member is approximately 1.3  \times 011 M\odot and average total luminous mass of group is  approximately 4.6 \times 011 M\odot.  The virial theorem has  used to estimate the virial mass.  The average Virial mass of group of  galaxies is approximately 6.3 \times 013 M\odot This is  attributed to the presence of large amount of dark matter which is  more than 90% in this group.  Hickson compact groups of galaxies are  unstable system due to the virial to luminous masses ratio.
