本章将综述行星宜居性与恒星辐射的深层关联。我们指出，长期恒星演化是驱动系外行星大气逃逸与气候变化的因素之一，同时也是恒星紫外辐射和高能粒子引发化学反应的源头。我们结合短期与长期恒星变异性及演化来阐释宜居性，梳理目前对恒星辐射的认知，以及为完善行星大气模型、筛选未来用于表征系外行星的最佳观测目标，还需了解的恒星辐射相关信息。
英文摘要
This chapter will review the deep connection of planetary habitability and stellar irradiation. We present the long-term stellar evolution as one of the drivers of atmospheric escape and climate changes on exoplanets, as well as the chemistry driven by stellar UV and stellar energetic particles. Habitability is presented in the context of short and long-term stellar variability and evolution to layout what we understand and what we need to know about stellar irradiation to constrain our planetary atmospheric models and choose the best targets for future missions that may characterize those exoplanets.
