The Influence of Cosmic Rays on Exoplanetary Atmospheric Biosignatures

宇宙射线对系外行星大气生物特征的影响

基本信息

项目摘要

The proposal will combine modeling expertise from atmospheric science with astroparticle physics to create the hitherto best predictions of potential atmospheric biosignatures outside the solar system. Planets in the habitable zones of their host stars are already being found, but mainly orbiting cooler stars, which are favored observational targets. However, the atmospheres of such planets are likely to be influenced by energetic particles and photons, so that biosignatures and their detectability have to be put into question. To address this issue consistently, we will trace energetic particles of Galactic or stellar cosmic rays through the exoplanetary magnetosphere and combine models describing the physical interactions in the atmosphere with 1D atmospheric chemistry-climate models, which then describe the effects on atmospheric biosignatures. We will perform a consistent iteration between climate variables, chemical constituents and air shower interactions between cosmic rays and the atmosphere, in order to predict the effect on key biosignatures such as ozone. We will calculate theoretical spectra to provide a link with next generation planned space missions such as the JWST and the E-ELT.
该提案将把大气科学的建模专业知识与天体粒子物理学结合起来,以创建迄今为止对太阳系外潜在大气生物特征的最佳预测。联合收割机。在其宿主恒星的宜居带中的行星已经被发现,但主要是绕着较冷的恒星运行,这是最受欢迎的观测目标。然而,这类行星的大气层很可能受到高能粒子和光子的影响,因此生物特征及其可探测性必须受到质疑。为了一致地解决这个问题,我们将追踪银河系或恒星宇宙射线的高能粒子通过系外磁层,并将描述大气中物理相互作用的联合收割机模型与一维大气化学气候模型相结合,然后描述对大气生物特征的影响。我们将在气候变量、化学成分和宇宙射线与大气之间的空气簇射相互作用之间进行一致的迭代,以预测对臭氧等关键生物特征的影响。我们将计算理论光谱,以提供与下一代计划的太空任务,如JWST和E-ELT的联系。
