摘要: 根据1997年3月至5月在上海天文台观测到的海尔波普彗星的旋喷流观测资料,利用MonteCarlo方法对旋喷流结构的形成进行了数值模拟,模拟结果较好地再现了观测到的旋喷流形态.

关键词: 海尔-波普彗星, 旋喷流结构, Monte Carlo模拟

Abstract: Based on the observational data of comet Hale Bopp's spiral jet structure obtained in Shanghai Astronomical Observatory from March to May 1997,the formation of the spiral jet structure is simulated by using Monte Carlo method.A basic model is proposed and the effect of different parameters is discussed.The numerical results reproduce the observed jet morphology Satisfactorily.

Key words: comet Hale Bopp, spiral jet, Monte Carlo simulatio
