Dynamical Formation of Cataclysmic Variables in Globular Clusters
  The formation and evolution of X-ray sources in globular clusters is likely
to be affected by the cluster internal dynamics and the stellar interactions in
the cluster dense environment.Several observational studies have revealed a
correlation between the number of X-ray sources and the stellar encounter rate
and provided evidence of the role of dynamics in the formation of X-ray
binaries. We have performed a survey of Monte-Carlo simulations aimed at
exploring the connection between the dynamics and formation of cataclysmic
variables (CVs) and the origin of the observed correlation between the number
of these objects, $N_{\rm cv}$, and the stellar encounter rate, $\Gamma$.The
results of our simulations show a correlation between $N_{\rm cv}$ and $\Gamma$
as found in observational data, illustrate the essential role played by
dynamics, and shed light on the dynamical history behind this correlation. CVs
in our simulations are more centrally concentrated than single stars with
masses close to those of turn-off stars, although this trend is stronger for
CVs formed from primordial binaries undergoing exchange encounters, which
include a population of more massive CVs absent in the group of CVs formed from
binaries not suffering any component exchange.
