报告摘要

~~~~~~~~~~~~~

Ultra-hot Jupiter Kelt 9 b forces us to reconsider the existing models of the upper atmospheres of hot exoplanets, which were previously developed using the example of G or M-star systems, such as HD209458b and GJ436b. The unique conditions of interaction of the radiation of an A-class star with the atmosphere necessitate kinetic modeling of excited levels of elements, primarily the hydrogen atom. For Kelt9b, absorption was measured for several Balmer lines, and lines of a number of heavy elements, the quantitative interpretation of which is an actual task. In this work, for the first time, 3D modeling of the atmosphere of a planet with a close Roche lobe is implemented, taking into account the aeronomy and kinetics of excited hydrogen.

报告人简介:

Shaikhislamov Ildar Faritovich 教授现任俄罗斯科学院西伯利亚分院激光物理研究所研究部主任、副所长。他于 1988 年毕业于新西伯利亚国立大学物理系,之后在应用力学与理论物理研究所任职,1991 年起在激光物理研究所工作,先后担任初级研究员、高级研究员、首席研究员、副所长、代理所长等职务。Shaikhislamov 教授的研究领域广泛,涵盖等离子体动力学、磁场、电磁吸收、激光物理、太阳风、激波、黑洞环境以及行星能量转化等多个方向。他长期致力于系外行星大气的三维磁流体数值模拟研究,他们成功解释了多个系外行星系统在Ly-α He I 10830 Å等不同波段的观测信号,并系统研究了不同物理因素在大气逃逸演化过程中的作用,对揭示系外行星大气的结构与演化机制具有重要意义。
