Photopolarimetric Modelling of Cometary Dust

博士研究的主题将是对彗星的天文学数据进行建模，目的是恢复尘埃喷出物的结构和成分。建模结果将与太阳系的一般性质及其形成模型联系起来。通过调整和使用多球T矩阵代码来执行建模（Mackowski，D W & Mishchenko，MI 2011，“A multiple sphere T-matrix Fortran code for use on parallel computer clusters”，Journal of Quantitative Spectroscopy and Radiative Transfer，122（13），2182-2192）。该代码的输出将与彩色地图，偏振地图，和67 P彗星，这是在广泛的观测期间获得的ESO VLT和ING WTH的光谱偏振数据进行比较。

The subject of the PhD research will be to carry out modelling of photopolarimetric data of comets, with the aim of recovering the structure and composition of the dust ejecta. The modelling results will be linked to the general properties of the solar system and models of its formation. The modelling is performed by adapting and using the multi-sphere T-matrix code (Mackowski, D W & Mishchenko, M I 2011, "A multiple sphere T-matrix Fortran code for use on parallel computer clusters", Journal of Quantitative Spectroscopy and Radiative Transfer, 122(13), 2182-2192). The output of this code will be compared with colour maps, polarimetric maps, and spectropolarimetric data of comet 67P, which were obtained during extensive campaings at the ESO VLT and at the ING WTH.
