| Abstract: |
The inclusion of the radiation pressure effect in the classical Roche model can lead to a number of different geometrical configurations. It has also been shown that this is a possible situation in a binary system that contains at least one component of early spectral type where the effect is stronger. Here, we focus on the case of the outer contact configuration at the L2 Lagrange point. This corresponds to a new type of binaries, which we call Inverse Semi-Detached Binaries (ISDB), in contrast to the classical S-D systems. Furthermore, we present the implications of the action of the radiation pressure to the system from a geometrical, dynamical and evolutional point of view. We also present a possible candidate for this new type of binary systems. |
