What are the the structures and atmospheric compositions of exoplanets (planets beyond the Solar System)? Do they have strong magnetic fields and if so, how do those fields interact with their parent stars? What are the properties of those stars and their flare and spot activities? These questions are key to answering the question: "Can an exoplanet support life as we know it?" Accurate stellar properties are required for accurate values of exoplanet sizes and masses, and to understand conditions on (and inside) those worlds. What are the detailed birth processes of other suns and planetary systems? What are the properties of a red giant star (the fate of our Sun just before death)? What are the conditions inside hot massive stars (and in their strong winds) before they explode as supernovae, injecting heavy elements into space and influencing future generations of stars and planets? We must have better answers to questions like these if we're to improve our reading of the opening and closing chapters of the biography of our Sun and Solar System.

系外行星（太阳系以外的行星）的结构和大气成分是什么？它们是否具有强磁场？如果有，这些磁场如何与其母恒星相互作用？这些恒星的特性及其耀斑和斑点活动是什么？这些问题是回答以下问题的关键：“系外行星能否维持我们所知的生命？”需要准确的恒星属性来准确计算系外行星的大小和质量，并了解这些世界上（和内部）的条件。其他太阳和行星系统的详细诞生过程是怎样的？红巨星有什么特性（太阳死亡前的命运）？炽热的大质量恒星（以及它们的强风）在爆炸成超新星、将重元素注入太空并影响未来几代恒星和行星之前，其内部条件是什么？如果我们要提高对太阳和太阳系传记开头和结尾章节的阅读能力，就必须对此类问题有更好的答案。
