The energy transfer in W UMa binary stars

摘要：

The properties of W UMa binary stars are studied based on the well-determined physical parameters of 132 W UMa systems. It is found that the energy transfer rate has a maximum value at q ~ 0.58. The relation between the energy transfer rate and the temperature deviation is also investigated,and the temperature of the secondary component is related to the energy transfer rate.
