Samevatting]
Met die blote oog sien die mens honderde geisoleerde sterre in die naghemel. 'n Groot persentasie van hierdie sterre is eintlik sisteme bestaande uit twee sterre. Hierdie binêre sterre is onderhewig aan 'n fassinerende dinamika en wedersydse wisselwerking wat soms tot dramatiese en hoë energie gebeurtenisse lei. 'n Verskeidenheid van vindingryke sterrekundige waarnemings is nodig om genoeg inligting te versamel om die aard van hierdie sisteme en die prosesse wat in hulle plaasvind, te ontrafel.

Abstract
Even though the unaided eye see hundreds of isolated stars in the sky many of these are actually systems of two stars. These binary stars are subject to fascinating dynamics and interactions between each other, sometimes leading to dramatic and high energy events . Various ingenious astronomical observations are necessary to accumulate enough information to unravel the nature of these systems and the processes taking place in them.
