| Abstract: |
We survey some old and new theories of binary star formation, with emphasis on formation dynamics in the dynamical collapse and the later, slower, disk interaction stage. Likewise, we discuss different modes of planet formation. Despite the fact that the most promising scenarios of binary and planetary system formation are not following one unified scenario (binary formation being a more direct process than the multi-stage planet formation process), the common physics of resonant and tidal interaction of protostars and protoplanets with disks makes their early evolution somewhat related. We explain how the thinking of this relationship has evolved when, in addition to Lindblad resonances, corotational torques have begun to be studied. The observed pre-main-sequence binaries may be useful laboratories for studying the dynamics of the more difficult to observe process of planet formation. |
