The habitable zone and extreme planetary orbits.
The habitable zone for a given star describes the range of circumstellar distances from the star within which a planet could have liquid water on its surface, which depends upon the stellar properties. Here we describe the development of the habitable zone concept, its application to our own solar system, and its subsequent application to exoplanetary systems. We further apply this to planets i...
متن کاملExponential law as a more compatible model to describe orbits of planetary systems
According to the Titus-Bode law, orbits of planets in the solar system obey a geometric progression. Many investigations have been launched to improve this law. In this paper, we apply square and exponential models to planets of solar system, moons of planets, and some extra solar systems, and compare them with each other.
متن کاملTidal Decay of Close Planetary Orbits
The 4.2-day orbit of the newly discovered planet around 51 Pegasi is formally unstable to tidal dissipation. However, the orbital decay time in this system is longer than the main-sequence lifetime of the central star. Given our best current understanding of tidal interactions, a planet of Jupiter’s mass around a solar-like star could have dynamically survived in an orbit with a period as short...
متن کاملPlanetary orbits in the elliptic restricted problem
Numerical simulations are made within the frame of the elliptic plane restricted three-body problem, in order to search if stable orbits exist for planets around one of the two components in double stars. The ADS 12033 system is investigated here. Large stable planetary orbits, already known to exist (more precisely, known to be possible from the dynamical point of view) through a systematic ex...
متن کاملRandomness and Determinism : Why Are the Planetary Orbits Elliptical ?
Kepler attempted to prove Divine design in the system of the world but actually had to attribute the eccentricities of the planetary orbits to randomness. Kant and even Laplace supported Kepler’s conclusion although Newton had proved that the eccentricities depended on the velocities of planetary motion. However, the velocities themselves are random; the system of the world does not exclude ran...
