【摘要】：探测系外行星的主要目的是研究生命和可供地球生命生存的行星是否普遍存在这一基本科学问题.近20年来已有超过3000颗系外行星被发现,~1还有几千颗候选系外行星有待确认,其中疑似宜居系外行星的数量近20颗.未来十年疑似宜居系外行星的数目将大为增加.尽管目前对宜居系外行星大气观测的能力和科学结果还很有限,但可以预期未来20年对这一类行星大气的观测将成为行星科学研究的重要领域.本文根据当前系外行星大气科学发展的状态和主要科学问题,在对中国未来系外行星科学发展方向进行分析的基础上,提出一种比较可行的建议,即在近1~2年内有针对性地开展系外行星大气普查和系外行星高层大气观测的可行性论证和预研,并在5~10年内择一予以实施.
[Abstract]:The main purpose of exploring exoplanets is to study the basic scientific question of whether life and the planets available for the life of the earth are ubiquitous. Over the past 20 years, more than 3000 exoplanets have been discovered and thousands of candidate exoplanets have yet to be confirmed, of which nearly 20 are suspected to be habitable exoplanets. The number of suspected habitable exoplanets will increase dramatically over the next decade. Although the ability and scientific results of observing the atmosphere of habitable exoplanets are still very limited, it can be expected that the observation of this type of planetary atmosphere in the next 20 years will become an important field of planetary science research. On the basis of the analysis of the future development direction of exoplanet science in China, a more feasible suggestion is put forward according to the status and main scientific problems of the development of atmospheric science of exoplanets in the present system, and on the basis of the analysis of the future development direction of the science of exoplanets in China, That is to say, the feasibility demonstration and pre-study of the survey of the exoplanet atmosphere and the observation of the upper atmosphere of the extrasolar planets are carried out in the past 1 ~ 2 years, and they will be carried out in the next 5 ~ 10 years.
