Impact of Comet Shoemaker-Levy 9 on Jupiter: Modelling the First 200 Seconds

9322509 Mac Low 1994年7月，苏梅克-利维9号彗星的碎片将撞击木星。在碎片撞击后的前200秒内，将使用半解析方法和完整的流体动力学代码来模拟木星的大气。这些模型为空袭提供了初始条件。关键的一点是，这些撞击释放的能量足够大，以至于爆炸从大气中爆发出来。重点将放在开发空爆和火球的详细数值模拟上。主要目标将是产生光曲线，这可能是从伽利略和旅行者2号航天器上可以观察到的，或者是从位置良好的木星卫星上反射出来的。其他目标是预测抛出大气层的物质的数量和速度(以及可能重新进入大气层的地方)、上升到可能形成不寻常云的高海拔的质量的量，以及在大气中不同深度沉积的能量。M#PD 9322509 Mac Low苏梅克-利维9号彗星的碎片将于1994年7月撞击木星。半解析法与全Q SQ S！！；S S时代新罗马符号&Amp；宋体罗马翼部B字体1 MS LineDraw 2现代1信使5信使新栅栏MT Extra“h”e(E.克劳德特·梅里克·梅伦宁格

9322509 Mac Low The fragments of Comet Shoemaker-Levy 9 will strike Jupiter in July 1994. Semi-analytic methods and full hydrodynamics codes will be will be utilized to model Jupiter's atmosphere during the first 200 seconds after the impact of a fragment. These models provide initial conditions for the airburst. The key point is that the energy released by these impacts is large enough that the explosion breaks out of the atmosphere. the focus will be on developing detailed numerical simulations of the airburst and the fireball. The primary goal will be to produce light curves, as might be observable from the Galileo and Voyager 2 spacecraft, or as reflected off well-placed Jovian satellites. Other goals are to predict the amount and velocity of material thrown out of the atmosphere (and where it might be expected to re-enter the atmosphere), the amount of mass raised to high altitudes where unusual clouds might form, and the energy deposited at various depths in the atmosphere.
