彗星中含有压力下的尘埃和气体的空腔的上边界的位置

Location of upper borders of cavities containing dust and gas under pressure in comets

Sergei I. Ipatov

摘要:

如果DI瞬时撞击坑的直径约为150-200米,则9 P/Tempel 1号彗星撞击前的表面与深度撞击号航天器撞击舱与彗星碰撞后物质喷射过程中挖掘的最大空洞的上边界之间的距离估计约为5-6米。在直径为100 m时,估计距离为4 m。这一结果表明,位于彗星表面以下几米处的含有压力下的尘埃和气体的空洞可能是频繁的。

英文摘要:

The distance between the pre-impact surface of Comet 9P/Tempel 1 and the upper border of the largest cavity excavated during ejection of material after the collision of the impact module of the Deep Impact spacecraft with the comet is estimated to be about 5-6 metres if the diameter of the DI transient crater was about 150-200 m. The estimated distance was 4 m at the diameter was 100 m. This result suggests that cavities containing dust and gas under pressure located a few metres below surfaces of comets can be frequent.
