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

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

Direct N-body Simulations of Satellite Formation around Small Asteroids: Insights from DART’s Encounter with the Didymos System

The Planetary Science Journal
We explore binary asteroid formation by spin-up and rotational disruption considering the NASA DART mission's encounter with the Didymos–Dimorphos binary, which was the first small binary visited by a spacecraft.

Photometric Observations and Analysis of Active Asteroid (62412) 2000 SY178

The Astronomical Journal
The active asteroid (62412) 2000 SY178 is a C-type object located in the outer main belt and was first reported to exhibit a dust tail in 2014 May. Before and after its recent perihelion, we carried out long-term observations of 2000 SY178 with the ...
