新的研究显示,像Arrorokath这样的冰冷Kuiper带物体可能通过温和重力崩溃而不是暴力冲击形成。 A new study shows icy Kuiper Belt objects like Arrokoth likely formed via gentle gravitational collapse, not violent impacts.

密歇根州立大学的一项研究表明,像阿罗科斯一样,Kuiper带中的冰“雪人”形状可能通过引力崩溃而不是暴力碰撞形成。 A Michigan State University study reveals that icy "snowman" shapes in the Kuiper Belt, like Arrokoth, likely formed through gravitational collapse rather than violent collisions. 研究人员利用高分辨率模拟,显示尘埃和石块的旋转云云可以分裂和轻轻地融合到接触的二进制中,从而保持其结构。 Using high-resolution simulations, researchers show rotating clouds of dust and pebbles can split and gently merge into contact binaries, preserving their structure. 该模型说明物质强度,产生符合观测结果的现实的象雪人一样的物体,为这些物体的形成提供了第一种实际可信的解释。 The model, which accounts for material strength, produces realistic snowman-like objects consistent with observations, offering the first physically plausible explanation for their formation.
