The Dynamics of Neptune Trojan: I. the Inclined Orbits
The stability of Trojan type orbits around Neptune is studied. As the first part of our investigation, we present in this paper a global view of the stability of Trojans on inclined orbits. Using the frequency analysis method based on the FFT technique, we construct high resolution dynamical maps on the plane of initial semimajor axis a0 versus inclination i0. These maps show three most stable ...
متن کاملTowards a Theory for the Origin of Neptune Trojans
The newly discovered class of Neptune Trojans promises to test theories of planet formation by coagulation. Neptune Trojans resembling the prototypical object 2001 QR322 (“QR”)—whose radius of ∼100 km is comparable to that of the largest Jupiter Trojan—may outnumber their Jovian counterparts by a factor of ∼20. We develop and test three theories for the origin of large Neptune Trojans: pull-dow...
متن کاملA thick cloud of Neptune Trojans and their colors.
The dynamical and physical properties of asteroids offer one of the few constraints on the formation, evolution, and migration of the giant planets. Trojan asteroids share a planet's semimajor axis but lead or follow it by about 60 degrees near the two triangular Lagrangian points of gravitational equilibrium. Here we report the discovery of a high-inclination Neptune Trojan, 2005 TN(53). This ...
متن کاملRelative Dynamics and Control of Spacecraft Formations in Eccentric Orbits
Formation ying is a key technology for both deep-space and orbital applications that involve multiple spacecraft. Many future space applications will bene t from using formation ying technologies to perform distributed observations (e.g., synthetic apertures for Earth mapping interferometry) and to provide improved coverage for communication and surveillance. Previous research has focused ...
متن کاملType Ii Migration of Planets on Eccentric Orbits
The observed extrasolar planets possess both large masses (with a median M sin i of 1.65 MJ) and a wide range in orbital eccentricity (0 < e < 0.94). As planets are thought to form in circumstellar disks, one important question in planet formation is determining whether, and to what degree, a gaseous disk affects an eccentric planet’s orbit. Recent studies have probed the interaction between a ...
