Resum

The importance of stability in the three-body problem will be discussed 
in the context of three physical applications. Specifically the 
destruction of globular clusters as the orbit the galaxy; the disruption 
of stellar binaries by the massive black hole in the centre of the Milky 
Way; and a new method for discovering low mass extrasolar planets which 
are not detectable using available methods. This work was carried out 
during my PhD candidature at Monash University (Melbourne, Australia) 
based on a new formulism developed by Rosemary A. Mardling that predicts 
the long-term stability of three-body problem systems. This formulism 
predicts systems that are unstable to the eventual escape of one of the 
masses in a random walk process and can be applied to the general 
three-body problem.
