How Eccentric Orbital Solutions Can Hide Planetary Systems in 2:1 Resonant Orbits
The Doppler technique measures the reflex radial motion of a star induced by the presence of companions and is the most successful method to detect exoplanets. If several planets are present, their signals will appear combined in the radial motion of the star, leading to potential misinterpretations of the data. Specifically, two planets in resonant orbits can mimic very efficiently the signal ...
متن کاملSingle Close Encounters Do Not Make Eccentric Planetary Orbits
The recent discovery of a planet in an orbit with eccentricity e = 0.63± 0.08 around the Solar-type star 16 Cyg B, together with earlier discoveries of other planets in orbits of significant eccentricity, raises the question of the origin of these orbits, so unlike the nearly circular orbits of our Solar system. In this paper I consider close encounters between two planets, each initially in a ...
متن کاملOrbital Resonances in Planetary Systems
There are two main types of resonance phenomena in planetary systems involving orbital motions: (i) mean motion resonance: This is intuitively the most obvious type of resonance; it occurs when the orbital periods of two planets are close to a ratio of small integers; (ii) secular resonance: this is a commensurability of the frequencies of precession of the orientation of orbits, as described b...
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 کاملFuzzy Sliding Mode for Spacecraft Formation Control in Eccentric Orbits
The problem of relative motion control for spacecraft formation flying in eccentric orbits is considered in this paper. Due to the presence of nonlinear dynamics and external disturbances, a robust fuzzy sliding mode controller is developed. The slopes of sliding surfaces of the conventional sliding mode controller are tuned according to error states using a fuzzy logic and reach the pre-define...
