Dynamical Habitability of Planetary Systems [PDF]
Astrobiology, 2010 The problem of the stability of planetary systems, a question that concerns only multiplanetary systems that host at least two planets, is discussed. The problem of mean motion resonances is addressed prior to discussion of the dynamical structure of the more than 350 known planets.

Fluid Dynamics Experiments for Planetary Interiors [PDF]
Surveys in Geophysics, 2021 AbstractUnderstanding fluid flows in planetary cores and subsurface oceans, as well as their signatures in available observational data (gravity, magnetism, rotation, etc.), is a tremendous interdisciplinary challenge. In particular, it requires understanding the fundamental fluid dynamics involving turbulence and rotation at typical scales well beyond

The dynamics of Planetary Nebulae [PDF]
Symposium - International Astronomical Union, 1997 In this review we focus on new observations and theory that directly pertain to understanding the hydrodynamic evolution of planetary nebulae (PNe). The recent history of the field lead us to break the review into two parts, macroscopic and microscopic structures, since both the size scales and the dominant physics appear to cleave nicely into more-or ...

Hybrid symplectic integrators for planetary dynamics [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 Abstract Hybrid symplectic integrators such as MERCURY are widely used to simulate complex dynamical phenomena in planetary dynamics that could otherwise not be investigated. A hybrid integrator achieves high accuracy during close encounters by using a high-order integration scheme for the duration of the encounter while otherwise using ...

A Generalized Dynamic Model and Coupling Meshing Force Analysis for Planetary Gear Set Transmissions
Applied Sciences, 2022 The dynamics analysis of a planetary gear set transmissions requires the creation of completely different models for different gears, which is very tedious. In this paper, a generalized dynamics modeling process is proposed for a three planetary gear set

A balanced state consistent with planetary-scale motion for quasi-geostrophic dynamics
Tellus: Series A, Dynamic Meteorology and Oceanography, 2020 The role of planetary-scale zonally-asymmetric thermal forcing on large-scale atmospheric dynamics is crucial for understanding low-frequency phenomena in the atmosphere. Despite its paramount importance, good theoretical foundation for the understanding

Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.
