The Solar system is the seat of many interactions between the Sun, the planets and their natural satellites. Moreover, since 1995, a large number of extrasolar planetary systems has been discovered where planets orbit around other stars, sometimes very close to them. Therefore, in such systems, tidal interactions are one of the key mechanisms that must

In this chapter we give an overview of the properties of our planetary system — both those related to its dynamical structure, namely the orbital and rotational motions of the constituent bodies, and those connected with their physical nature (e.g., size, composition, the presence of an atmosphere and/or of a solid surface).

Planetary nebulae in planetary and binary systems
Astrophysics and Space Science, 1981The problem of the survival of a low-mass secondary orbiting a primary that becomes a planetary nebula is studied. The values of the mass of the primary are 1.0, 1.5, and 2.0M ⊙; the values of the mass of the secondary 0.001M ⊙, 0.01M ⊙ and 0.1M ⊡.

On the Spacing of Planetary Systems
Physical Review Letters, 2000We present a simplified model of planetary accretion based on conservation of mass, conservation of momentum, and angular-momentum-deficit stability. Within the limitations of this model, we show how the organization of generic planetary systems may be derived from the knowledge of their initial mass distribution.

The formation of the planetary system
Celestial Mechanics, 1984One of the most challenging problems of natural science is the question of how our solar system was formed some 4,6 billion years ago. The main difficulties encountered in trying to find any definite answer to this problem are twofold. In the first place we cannot design direct experiments which could give us clues to the relative importance of the ...

A Planetary Park system for Mars
Space Policy, 2004The increasing robotic exploration of Mars and eventual human exploration and settlement of that planet threatens to have a significant environmental impact on scientifically important sites and sites of natural beauty in the form of contamination with micro-organisms and spacecraft parts.

Resonances in Multiple Planetary Systems
Celestial Mechanics and Dynamical Astronomy, 2004The authors investigate the dynamical stability of real extra-solar two-planet planetary systems HD 74156, HD 38529, HD 168443 and HD 169830. The reasons to choose these planets are: (a) they were not analyzed from the dynamical point of view before; (b) the two discovered planets of each system are far away from mean motion resonance; (c) the regions ...
