主序星环境中的天体生物学：光球辐射的影响
Astrobiology in the Environments of Main-Sequence Stars: Effects of Photospheric Radiation
摘要：
我们探索在太阳以外的恒星环境中的碳基大分子（如DNA）是否能够在光球恒星辐射（如UV-C）的影响下生存下来。因此，我们主要关注光谱类型为F、G、K和M的主序星。重点是研究恒星宜居带的辐射环境。恒星宜居带与天体生物学有关，因为它们构成了星周区域，在这些区域中，适当大小的行星可以保持表面温度，使水以流体形式存在，从而增加了地球型生命的可能性。
英文摘要：
We explore if carbon-based macromolecules (such as DNA) in the environments of stars other than the Sun are able to survive the effects of photospheric stellar radiation, such as UV-C. Therefore, we focus on main-sequence stars of spectral types F, G, K, and M. Emphasis is placed on investigating the radiative environment in the stellar habitable zones. Stellar habitable zones are relevant to astrobiology because they constitute circumstellar regions in which a planet of suitable size can maintain surface temperatures for water to exist in fluid form, thus increasing the likelihood of Earth-type life.
