Exploring the orbital evolution of planetary systems [PDF]

open access: yesEuropean Journal of Physics, 2017
The aim of this paper is to encourage the use of orbital integrators in the classroom to discover and understand the long term dynamical evolution of systems of orbiting bodies. We show how to perform numerical simulations and how to handle output data in order to reveal the dynamical mechanisms that dominate the evolution of arbitrary planetary ...

On the dynamical evolution of a young planetary system [PDF]

open access: yes, 2020
The dynamical evolution of planetary and protoplanetary structures represents one of the major challenges for the modern Computational Astrophysics. The focus of our investigation is to study the dynamical evolution of a young planetary system both in isolation as well as embedded in a typical stellar open cluster.

Long extra-tropical planetary wave propagation in the presence of slowly varying mean flow and bottom topography. II: ray propagation and comparison with observations [PDF]

open access: yes, 2003
Ray theory is used to predict phase and group velocities for long planetary waves under realistic, albeit slowly varying, oceanic conditions. The results are compared with local theory using fields smoothed to the same amount (9° latitude/longitude) as ...

A magnetic measurement technique for small rare samples: Pre-study for Chang’e-5 returned and other extraterrestrial samples

open access: yesFrontiers in Earth Science, 2023
Standard-size samples are usually used for traditional paleomagnetic studies. In some cases, small irregular samples are employed considering their amount and magnetic strength as well as experiment efficiency.

Theoretical models of planetary system formation II. Post-formation evolution [PDF]

open access: yes, 2015
Aims. We extend the results of planetary formation synthesis by computing the long-term evolution of synthetic systems from the clearing of the gas disk into the dynamical evolution phase. Methods.

A ring system detected around the Centaur (10199) Chariklo [PDF]

open access: yes, 2014
Hitherto, rings have been found exclusively around the four giant planets in the Solar System1. Rings are natural laboratories in which to study dynamical processes analogous to those that take place during the formation of planetary systems and galaxies.

The New Generation Planetary Population Synthesis (NGPPS) [PDF]

open access: yes, 2021
Context. Planetary formation and evolution is a combination of multiple interlinked processes. Constraining the mechanisms observationally requires statistical comparison to a large diversity of planetary systems. Aims.

A New Health Condition Detection Method for Planetary Gears Based on Modified Distributed Compressed Sensing and Multiscale Symbol Dynamic Entropy

open access: yesShock and Vibration, 2021
Planetary gear transmission system is an important transmission part of large machinery and is prone to failure. Aiming at the problem of how to extract fault information from vibration signals of nonlinear and nonstationary planetary gearboxes, a ...
