系外行星和SETI

Exoplanets and SETI

Jason T. Wright

摘要:

系外行星的发现既集中又扩大了对外星智慧生命的探索。考虑到地球是一颗系外行星,对单个系外行星轨道参数的了解,以及我们对整个星系系外行星普遍存在的新理解,都通过激发新的“谢林点”(即信标的最佳搜索策略)改变了SETI通信工作的搜索策略。未来通过成像和过境,用光度和光谱来表征单个行星的努力,也将允许在其表面,大气层和轨道上搜索各种技术特征。在短期内,对新的行星系的研究甚至可能会发现自由漂浮的巨型结构。

英文摘要:

The discovery of exoplanets has both focused and expanded the search for extraterrestrial intelligence. The consideration of Earth as an exoplanet, the knowledge of the orbital parameters of individual exoplanets, and our new understanding of the prevalence of exoplanets throughout the galaxy have all altered the search strategies of communication SETI efforts, by inspiring new "Schelling points" (i.e. optimal search strategies for beacons). Future efforts to characterize individual planets photometrically and spectroscopically, with imaging and via transit, will also allow for searches for a variety of technosignatures on their surfaces, in their atmospheres, and in orbit around them. In the near-term, searches for new planetary systems might even turn up free-floating megastructures.
