The Material Point Method (MPM) for simulating hypervelocity impact on asteroids
Xiaoran Yan, Patrick Michel, Ruichen Ni +2
Shock-physics numerical codes are essential tools for describing the short but extreme fragmentation stage of the hypervelocity impact process on asteroids. However, accurately rep…
Investigating tidal stripping of a pre-existing moon as the origin of Saturn's young icy rings
Yifei Jiao, Francis Nimmo, Jack Wisdom +1
The origin of Saturn's rings has been debated for decades. Measurements from Voyager and Cassini have suggested that the rings could be as young as ~100 Myr and composed of nearly…
The Detectability of Lunar-Origin Asteroids in the LSST Era
Yixuan Wu, Yifei Jiao, Wen-Yue Dai +5
While most near-Earth asteroids (NEAs) are thought to originate from the main belt, recent discoveries have suggested the existence of a lunar-derived NEA population, such as the a…
Probing the Moon from Future Asteroid Impacts: A Review
Yifei Jiao, Bin Cheng, Hexi Baoyin
The Earth--Moon system has been experiencing impacts from asteroids and comets for billions of years. The Moon, as an airless body, has preserved a distinct record of these events…
