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…
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…
Asteroid Kamo`oalewa's journey from the lunar Giordano Bruno crater to Earth 1:1 resonance
Yifei Jiao, Bin Cheng, Yukun Huang +6
Among the nearly 30,000 known near-Earth asteroids (NEAs), only tens of them possess Earth co-orbital characteristics with semi-major axes 1 au. In particular, 469219 Kamo`oa…
