New Interpretation of Superhumps
arXiv:0902.2880
Abstract
Observational evidence is presented for periodically variable irradiation of secondary components. This results in strongly modulated mass outflow. Superhumps are then due to enhanced dissipation of the kinetic energy of the stream. Qualitative interpretation of superhump periods and their variations is also presented.
