Asteroid lightcurves from the Palomar Transient Factory survey: Rotation periods and phase functions from sparse photometry [PDF]

, 2015
We fit 54,296 sparsely-sampled asteroid lightcurves in the Palomar Transient Factory to a combined rotation plus phase-function model. Each lightcurve consists of 20+ observations acquired in a single opposition.

On the Particular Dynamics of Rubble-Pile Asteroid Rotation Following Projectile Impact on the Surface During Planetary Approach [PDF]

Mathematics
The main motivation of this research is the semi-analytical exploration of the dynamics of an asteroid that is attacked while approaching a planet (with an inelastic collision of the projectile normally to the surface of the asteroid occurring just ...

Optimized Asteroid Rotation and Shape Modeling through an Integrated Shape-from-silhouette and Optical Flow Approach

The Astronomical Journal
Asteroids offer valuable insights into the formation and evolution of the solar system. Understanding their rotation and shape is essential for studying asteroid collision histories and geological processes, as well as for planning exploration missions ...

Lightcurves, Rotation Periods, and Colors for Vera C. Rubin Observatory’s First Asteroid Discoveries

The Astrophysical Journal Letters
We present lightcurves, rotation periods, and colors for the first asteroid discoveries made with the NSF-DOE Vera C. Rubin Observatory. These are the first science results derived from the 2103 asteroid discoveries released as part of the Rubin First ...

A Change of the Rotation Period of Asteroid (65803) Didymos Caused by the DART Impact

The Planetary Science Journal
On 2022 September 26, the NASA Double Asteroid Redirection Test (DART) spacecraft impacted Dimorphos, the secondary component of the binary asteroid (65803) Didymos. This experiment tested the kinetic impactor technology for diverting dangerous asteroids.

Inelastic Collision Influencing the Rotational Dynamics of a Non-Rigid Asteroid (of Rubble Pile Type)

Mathematics, 2023
We have considered here a novel particular model for dynamics of a non-rigid asteroid rotation, assuming the added mass model instead of the concept of Viscoelastic Oblate Rotators to describe the physically reasonable response of a ‘rubble pile ...

Physical Properties of the Young Asteroid Pair 2010 UM26 and 2010 RN221

The Astronomical Journal, 2023
The main belt asteroids 458271 (2010 UM26) and 2010 RN221 share almost identical orbital elements, and currently appear as comoving objects ∼30″ apart in the plane of the sky.

Habitat Bennu: Design Concepts for Spinning Habitats Constructed From Rubble Pile Near-Earth Asteroids

Frontiers in Astronomy and Space Sciences, 2022
The authors explore the possibility that near-earth, rubble pile asteroids might be used as habitats for human settlement by increasing their rotation to produce spin gravity. Using previously published scaling by Maindl et al.
