 Non-Conservative Evolutions of Close Binary Systems

 Binary stars are very unique tools for determining absolute properties of
 stars. Since we are calibrating our stellar models based on these data,
 we need to understand the effect of binarity on the components evolutions.
 Although the role of mass transfer has been known for half century, some
 a priori assumptions needs to be revised. In this talk, I would present
 preliminary results on the efficiency of mass transfer based on the
 latest observational data. The effect of mass and angular momentum loss
 for producing Algol binaries will be discussed.
