Binary Collisions and the Slingshot Effect
, 2008 We derive the equations for the gravity assist manoeuvre in the general 2D case without the constraints of circular planetary orbits or widely different masses as assumed by Broucke, and obtain the slingshot conditions and maximum energy gain for ...

Encoding Cumulation to Learn Perturbative Nonlinear Oscillatory Dynamics
Advanced Science, Volume 13, Issue 25, 4 May 2026.Weak nonlinearities critically shape the long term behavior of oscillatory systems but are difficult to identify from data. A data‐driven framework is introduced to infer governing equations of weakly nonlinear oscillators from sparse and noisy observations.

Dynamical Structures Associated with High-Order and Secondary Resonances in the Spin–Orbit Problem
The Astronomical JournalIn our solar system, spin–orbit resonances are common under Sun–planet, planet–satellite, and binary asteroid configurations. In this work, high-order and secondary spin–orbit resonances are investigated by taking numerical and analytical approaches ...

Archives of impact: The politics of craters on Earth
Geographical Research, Volume 64, Issue 2, May 2026.This paper examines Earth’s 195 confirmed impact craters as archives, exploring their cataloguing and presentation as heritage sites. It argues Western scientific framings using military language and emphasising catastrophe overlook settler colonialism’s violent histories and marginalise indigenous earth‐sky cosmologies.

Transactions of the International Astronomical Union, 1979 This report is organized according to twelve subjects of interest in modern celestial mechanics. Emphasis is placed on the results of an exhaustive literature search in which assistance was received from several members of Commission 7. The impetus on celestial mechanics by space projects, by new observational techniques and by the use of high speed ...
