Asteroid models from the Lowell Photometric Database

open access: yes, 2016
We use the lightcurve inversion method to derive new shape models and spin states of asteroids from the sparse-in-time photometry compiled in the Lowell Photometric Database.

Puzzling rotation of asteroid 288 Glauke [PDF]

open access: yesAstronomy & Astrophysics, 2003
Most asteroids rotate about their axis of maximum moment of inertia. However, for several small asteroids with very slow rotation rates, the damping time scale is expected to be longer than the age of the Solar System, implying that these objects may exhibit non-principal axis rotation.

Rotation Periods of Asteroids Determined With Bootstrap Convex Inversion From ATLAS Photometry

open access: yesFrontiers in Astronomy and Space Sciences, 2022
The rotation period is one of the fundamental physical characteristics of asteroids. It can be determined from photometric measurements by standard methods of time-series period analysis or by creating a physical model of an asteroid with the rotation ...

Stability and Motion around Equilibrium Points in the Rotating Plane-Symmetric Potential Field

open access: yes, 2018
This study presents a study of equilibrium points, periodic orbits, stabilities, and manifolds in a rotating plane symmetric potential field. It has been found that the dynamical behaviour near equilibrium points is completely determined by the structure

First Results of the VLBI Experiment on Radar Location of the Asteroid 2012 DA14

open access: yesOpen Astronomy, 2013
An international VLBI experiment on radio location of the asteroid 2012 DA14 was organized on 2013 February 15–16, during its flyby close to Earth. The purpose of observations was to investigate and specify orbital parameters of the asteroid, as well as ...

Determination of 1929 Asteroid Rotation Periods from WISE Data

open access: yesThe Planetary Science Journal, 2023
We used 22 μ m (W4) Wide-field Infrared Survey Explorer (WISE) observations of 4420 asteroids to analyze lightcurves, and determined spin period estimates for 1929 asteroids.

Asteroid Models from Multiple Data Sources

open access: yes, 2015
In the past decade, hundreds of asteroid shape models have been derived using the lightcurve inversion method. At the same time, a new framework of 3-D shape modeling based on the combined analysis of widely different data sources such as optical ...

Orbital Mechanics near a Rotating Asteroid [PDF]

open access: yesJournal of Astrophysics and Astronomy, 2014
This study investigates the different novel forms of the dynamical equations of a particle orbiting a rotating asteroid and the effective potential, the Jacobi integral, etc. on different manifolds. Nine new forms of the dynamical equations of a particle orbiting a rotating asteroid are presented, and the classical form of the dynamical equations has ...

Scaling forces to asteroid surfaces: The role of cohesion

open access: yes, 2010
The scaling of physical forces to the extremely low ambient gravitational acceleration regimes found on the surfaces of small asteroids is performed. Resulting from this, it is found that van der Waals cohesive forces between regolith grains on asteroid ...

Neil Gehrels–Swift Observatory’s Ultraviolet/Optical Telescope Observations of Small Bodies in the Solar System

open access: yesUniverse, 2023
The Neil–Gehrels Swift Observatory has added extensively to our understanding of small bodies in our solar system through its capabilities to rapidly respond to short-live events such as outbursts and collisions, through its near-ultraviolet coverage ...
