This study explores the heteroclinic connections linking the stable and unstable manifolds of periodic orbits within the framework of the Sun-Jupiter planar restricted three-body problem.

The Yarkovsky Effect on the Long-term Evolution of Binary Asteroids

Wen-Han 文翰 Zhou 周 et al. (2024). The Astrophysical Journal Letters

By developing and numerically verifying an analytical model that includes Yarkovsky–Schach and planetary thermal effects, the researchers demonstrated that the Yarkovsky force significantly impacts mutual binary orbits. This orbital evolution occurs specifically in non-synchronous systems, where the spin and orbital periods differ, opening up new possibilities for understanding how binary systems migrate over time.

This study provides comprehensive data on Yarkovsky-driven changes in eccentricity and longitude of periapse. By exploring a broad range of physical and orbital parameters, the results complement the drift rates in semi-major axis previously established by Spitale and Greenberg (2001).

It is shown that the average thermal inertia of a sample of NEAs in the km-size range is 200 ± 40 J m^−2 s^−0.5 K^−1 and it is identified a trend of increasing thermal inertia with decreasing asteroid diameter.

Arecibo radar ranging of NEA 6489 Golevka (diameter ~ 0.5 km) confirms the presence of Yarkovsky-driven orbital drift. This non-gravitational perturbation was isolated by comparing the asteroid's observed trajectory against purely Newtonian dynamical models.

The Yarkovsky Effect on the Long-term Evolution of Binary Asteroids

Wen-Han 文翰 Zhou 周 et al. (2024). The Astrophysical Journal Letters

By developing and numerically verifying an analytical model that includes Yarkovsky–Schach and planetary thermal effects, the researchers demonstrated that the Yarkovsky force significantly impacts mutual binary orbits. This orbital evolution occurs specifically in non-synchronous systems, where the spin and orbital periods differ, opening up new possibilities for understanding how binary systems migrate over time.

By measuring non-gravitational orbital drift, this study identifies the Yarkovsky effect across the NEA population. The reliability of these detections is maintained through a high-precision model—incorporating relativistic terms and the mass of 16 large asteroids—combined with specialized astrometric error treatment.

The Yarkovsky effect for 99942 Apophis

David Vokrouhlický et al. (2015). Icarus

They used the determined rotation state, shape, size and thermophysical model of Apophis to predict the strength of the Yarkovsky effect in its orbit.

In this paper was investigated the possibility of detecting the Yarkovsky effect via precise orbit determination of near-Earth asteroids.

Failures and optimization in computation of asteroid synthetic proper elements

Zoran Knežević (2025). Celestial Mechanics and Dynamical Astronomy

The purpose of this paper is to draw attention to failures in computation of asteroid synthetic proper elements with a goal to point out the dynamical or computational causes of the failures.

They computed Lyapunov times for a sample of trans-Neptunian objects and outer main-belt asteroids using three numerical approaches: the variational method and two implementations of the renormalization technique.

It is studied the dynamical orbital and physical evolution of all 21 numbered and 13 selected unnumbered asteroids in retrograde orbits. They computed their starting orbital elements, absolute magnitudes, and diameters, together with the non-gravitational parameters A2 and da/dt.
