Comparing binary systems from rotating parent gas structures with
  different total masses
  In this paper we continue the investigation reported by \cite{RMAA}
concerning the morphology of binary configurations obtained via the collapse of
rotating parent gas structures with total masses in the range of M$_T$= 1 to 5
M$_{\odot}$. Here we extend the mass range and consider the collapse of two
uniform gas clumps of M$_T$= 50 and 400 M$_{\odot}$, so that they also rotates
rigidly in such a way that its approximate virial parameter takes the values of
0.5, 1.5, and 2.5 and their collapse is induced initially by implementing an
azimuthal mass perturbation. To assess the effects of the total mass of the
parent gas structure on the nature of the resulting binary configurations, we
also consider the collapse of two cores of M$_T$= 1 and 5 M$_{\odot}$. We
calculate the collapse of all these parent gas structures using three values of
the ratio of thermal energy to potential energy and for two values of the mass
perturbation amplitude. We next calculate the binary separations, masses and
integral properties of the binary fragments and present them in terms of the
total mass of the parent structure. For most of our models, we finally
calculate the $\beta$ extreme value, so that a model with a slightly higher
$\beta$ value would no longer collapse.
