Kant (1755) and Laplace (1796) built own hypothesis on the idea of Sun and planets forming from scattering substance in space. It is well-known the main difficult of the Kant-Laplace hypothesis consists in appearance of angular momentum exploring. The next step in cosmogony was the Jeans hypothesis.
Beginning with 40-years XX the great works have been carried out in cosmogony (e.g., Veizsacker (1943), Schmidt (1944)). Academician O. Schmidt (1944) proposed the model to origin of planets and their satellites based on a statistical low of distribution of specific angular momentum. However, Schmidt’s model was not able to explore the origin of gas-dust cloud around the Sun. In the past years modified models for planet forming have been proposed.
In this connection the purpose of this session is to offer an opportunity to explore, develop and promote the realistic models of origin of planetary system (in particular, Solar system). Obviously, construction of realistic models for forming planet is impossible without achievement in gravitation theory. Since the discovery by I. Newton of the universal gravitation law, and later the creation by A. Einstein of the general relativity the interest to this field of research has not lessened, which is testified by a great number of works. In spite of considerable successes of the general relativity the nature of the gravitational interaction has not been completely revealed, especially in what concerns the quantum theory of gravitation. As a consequence, in the 60s and 90s of the current century there were proposed alternative models of the gravitation theory (e.g. the Brance-Dicke theory (1964)). According to Schiff's hypothesis any gravitational theory of vitality reduces to postulates of the metric theory the main provisions of which are involved in the general relativity. The vitality criteria include the requirement that any theory should provide predictions of gravitational effects in a weak gravitational field, in particular, it should suggest corrections to predictions of the Newton theory. For exploring gravitational interactions and forces as the most universal ones some statements of self-organization theory can be used (for example, I. Prigogine (1989) proposed the cosmological approach of irreversible process for forming particles owing to gravitational energy expenses).
This session aims to encourage researchers to present their results (on models for planet forming, theory of gravity, astronomical observations, computer modeling and analysis of aerohydrodynamic processes), to explore methods and approaches, to exchange ideas and computer technologies on this topics, to gain some insight into the difficulties and solution approaches associated with the state of the art.
Papers are solicited on the following and related topics:
- development of models of origin of planetary system;
- usage of theory of gravity to forming planetary systems;
- application of self-organization theory to explore and develop the models of origin of Solar system;
- astronomical observations of planets of Solar system;
- computational aerohydrodynamics methods in application to models for planet forming;
- turbulent flow structures analysis and modeling in planetary atmospheres;
- modeling and prediction of complex processes based on nonlinear dynamics methods.
Suggested topics for presentation include, but are not limited to the mentioned above.
