Sumário           :
In this talk I will give a brief overview of cataclysmic variable stars with emphasis on evolutionary aspects. The possibility of brown dwarf like secondaries in some systems will be investigated, showing the evidence available up to now. I will conclude with a short presentation of recent results of the ROSAT source 1RXS J105010.3-140431 based on UVES and ISAAC spectroscopy
