The relationship between the `limiting' Yarkovsky drift speed and asteroid families' Yarkovsky V-shape [PDF]
Serbian Astronomical Journal, 2020 The Yarkovsky effect is an important force to consider in order to understand the long-term dynamics of asteroids. This non-gravitational force affects the orbital elements of objects revolving around a source of heat, especially their semi ...

Binary Asteroid Observation Orbits from a Global Dynamical Perspective [PDF]
, 2006 We study spacecraft motion near a binary asteroid by means of theoretical and computational tools from geometric mechanics and dynamical systems. We model the system assuming that one of the asteroids is a rigid body (ellipsoid) and the other a sphere ...

Dynamical Masses of 20 Asteroids Determined with Gaia DR3 Asteroid Observations
The Astronomical Journal, 2023 Abstract We combined the ground-based and Gaia Data Release 3 (DR3) asteroid observations to determine the masses of 20 asteroids with asteroid–asteroid close encounters. In order to take full advantage of the high-precision observations from Gaia, we use the Fisher information to select appropriate model parameters and the modified ...

The splitting of double-component active asteroid P/2016 J1 (PANSTARRS) [PDF]
, 2017 We present deep imaging observations, orbital dynamics, and dust tail model analyses of the double-component asteroid P/2016 J1 (J1-A and J1-B). The observations were acquired at the Gran Telescopio Canarias (GTC) and the Canada-France-Hawaii Telescope ...

Dynamics, Origin, and Activation of Main Belt Comets [PDF]
, 2009 The discovery of Main Belt Comets (MBCs) has raised many questions regarding the origin and activation mechanism of these objects. Results of a study of the dynamics of these bodies suggest that MBCs were formed in-situ as the remnants of the break-up of

DYNAMICAL EFFECTS FROM ASTEROID BELTS FOR PLANETARY SYSTEMS [PDF]
International Journal of Bifurcation and Chaos, 2004 The orbital evolution and stability of planetary systems with interaction from the belts is studied using the standard phase-plane analysis. In addition to the fixed point which corresponds to the Keplerian orbit, there are other fixed points around the inner and outer edges of the belt.

An Efficient Numerical Approach to Modeling the Effects of Particle Shape on Rubble-pile Dynamics
The Planetary Science Journal, 2023 We present an approach for the inclusion of nonspherical constituents in high-resolution N -body discrete element method (DEM) simulations. We use aggregates composed of bonded spheres to model nonspherical components.
