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

苏梅克-列维9号彗星的碎片将于1994年7月撞击木星。半解析方法和完整的流体力学代码将被用来模拟碎片撞击后200秒内木星的大气。这些模型为空爆提供了初始条件。关键的一点是，这些撞击释放的能量足够大，足以使爆炸脱离大气层。重点将放在发展空中爆炸和火球的详细数值模拟上。主要目标将是产生光曲线，就像伽利略号和旅行者2号宇宙飞船可以观察到的那样，或者是由定位良好的木星卫星反射出来的。其他目标是预测被抛出大气层的物质的数量和速度（以及它们可能重新进入大气层的地方），上升到可能形成不寻常云层的高海拔地区的质量，以及沉积在大气层不同深度的能量。苏梅克-列维9号彗星的碎片将于1994年7月撞击木星。半解析方法与满q问年代!!;！3 F s s Times New Roman Symbol & Arial Roman wingings B Script 1 MS LineDraw 2 Modern 1 Courier 5 Courier New Fences MT Extra " h " e(e(e)。克劳德特·梅里克·曼宁格

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.
