标题： Habitable Zones and UV Habitable Zones around Host Stars

摘要： 紫外线辐射对生命来说是一把双刃剑。如果它太强，地表生物系统将会受损；而如果它太弱，许多生化化合物的合成将无法进行。我们试图获得连续的紫外线宜居带，并将紫外线宜居带与宿主恒星的宜居带进行比较。利用紫外线宜居带的边界紫外线辐射，我们计算了质量从 0.08 到 4.00 \mo 的宿主恒星的紫外线宜居带。对于有效温度低于 4600 K 的宿主恒星，紫外线宜居带比宜居带更靠近恒星；对于有效温度高于 7137 K 的宿主恒星，紫外线宜居带比宜居带更远离恒星。对于热亚矮星作为宿主恒星的情况，紫外线宜居带的距离约为宜居带的十倍，这不适合生命存在。 显示英文摘要

摘要： Ultraviolet radiation is a double-edged sword to life. If it is too strong, the terrestrial biological systems will be damaged. And if it is too weak, the synthesis of many biochemical compounds can not go along. We try to obtain the continuous ultraviolet habitable zones, and compare the ultraviolet habitable zones with the habitable zones of host stars. Using the boundary ultraviolet radiation of ultraviolet habitable zone, we calculate the ultraviolet habitable zones of host stars with masses from 0.08 to 4.00 \mo. For the host stars with effective temperatures lower than 4,600 K, the ultraviolet habitable zones are closer than the habitable zones. For the host stars with effective temperatures higher than 7,137 K, the ultraviolet habitable zones are farther than the habitable zones. For hot subdwarf as a host star, the distance of the ultraviolet habitable zone is about ten times more than that of the habitable zone, which is not suitable for life existence.
