Abstract

         According to Chandra Survey Observatory Near-Asteroid Belt Comets, the solar wind's contact with the comet produces a variety of spectral characteristics. The study of X-ray spectra produced by charge exchange is presented here. The spectrum of a comet can reveal a lot about its composition. This study has concentrated on the elemental abundance in six different comets, including 17P/Holmes, C/1999T1, C/2013A1, 9p/Temple1, and 103p/Hartley2 (NEAT). Numerous aspects of the comet's dynamics allow it to behave in a unique manner as it gets closer to the Near-Asteroid Belt. These characteristics are being examined, and some studies are still ongoing. The computations allow us to observe, for instance, how the composition of a comet's upper atmosphere affects how much gas it produces. For several comet morphologies, both linear and nonlinear, bow shock, contact surface, and stagnation point are investigated in relation to gas production rate. Our results shed light on the complex interactions between cometary ions and the solar wind. An increase in gas production rate was shown to be significantly correlated with sharp drops in average molecular weight.

彗星大气近小行星带的x射线发射光谱分析
根据钱德拉近小行星带彗星巡天天文台的数据,太阳风与彗星的接触产生了各种光谱特征。本文介绍了电荷交换产生的x射线光谱的研究。彗星的光谱可以揭示它的很多成分。本研究集中研究了6颗不同彗星的元素丰度,包括17P/Holmes、C/1999T1、C/2013A1、9p/Temple1和103p/ hartle2 (NEAT)。彗星动力学的许多方面使它在接近近小行星带时表现出独特的方式。这些特征正在研究中,一些研究仍在进行中。计算使我们能够观察到,例如,彗星上层大气的组成如何影响它产生的气体量。对于几种彗星形态,包括线性和非线性,弓形激波、接触面和驻点与产气速率的关系进行了研究。我们的研究结果揭示了彗星离子和太阳风之间复杂的相互作用。产气速率的增加与平均分子量的急剧下降显著相关。
