313 New Asteroid Rotation Periods from Palomar Transient Factory Observations [PDF]

, 2014
A new asteroid rotation period survey has been carried out by using the Palomar Transient Factory (PTF). Twelve consecutive PTF fields, which covered an area of 87 deg^2 in the ecliptic plane, were observed in the R band with a cadence of ~20 minutes ...

Categorization of Spatial and Temporal Ejecta Outcomes in Binary Systems Based on Variations of the Didymos System

The Planetary Science Journal
With the increasing number of binary asteroid systems being discovered, ejecta studies must expand from solely investigating single-body systems to modeling more complex multiple-body systems. For example, the Double Asteroid Redirection Test provides an

Long-term Spectral Monitoring of Active Asteroid (6478) Gault: Implications for the H Chondrite Parent Body

The Planetary Science Journal
Active asteroid (6478) Gault underwent outbursts between late 2018 and early 2019 with tails morphologically similar to the ejecta from Dimorphous following the Double Asteroid Redirection Test impact.

Evidence for YORP-induced Spin Deceleration in Asteroid (433) Eros

The Astrophysical Journal
Theoretically, the Yarkovsky–O’Keefe–Radzievskii–Paddack (YORP) effect induced by thermal reemission from asteroid surfaces can either accelerate or decelerate their rotation.

ASTEROID COLLISIONAL EVOLUTION - AN INTEGRATED MODEL FOR THE EVOLUTION OF ASTEROID ROTATION RATES

, 1992
We combine experimental data and theoretical results to develop a model for the changes in the rotation rates of fragments produced by large collisions that break up and disperse asteroidal targets.

Dimorphos’s Orbit Period Change and Attitude Perturbation due to Its Reshaping after the DART Impact

The Planetary Science Journal
On 2022 September 26 (UTC), NASA's Double Asteroid Redirection Test (DART) mission achieved a successful impact on Dimorphos, the secondary component of the near-Earth binary asteroid system (65803) Didymos. Subsequent ground-based observations suggest a

Shape and spin of asteroid 967 Helionape

, 2017
Knowledge of the spin and shape parameters of the asteroids is very important for understanding of the conditions during the creation of our planetary system and formation of asteroid populations.

Considering Contact Forces during the Formation of Planetesimals by Gravitational Collapse: Mutual Orbits, Spin States, and Shapes

The Astrophysical Journal
In this work, we apply a soft-sphere discrete element method (SSDEM) within the PKDGRAV N -body integrator to investigate the formation of planetesimal systems through the gravitational collapse of clouds of superparticles. Previously published numerical
