论文摘要
寻找宇宙其他地方的不同生命形式是天体物理学和天体生物学研究的迷人领域。目前，根据NASA系外行星档案数据库，已经发现了3876个系外行星。地球相似指数（ESI）定义为半径，密度，逃逸速度和表面温度的几何平均值，范围为0（与地球不同）到1（类似于地球）。 ESI的创建是根据与地球相似的基础来索引系外行星的。在本文中，我们检查了岩石系外行星的物理条件可能适合于依赖岩石的极端粒子的生存，例如蓝细菌的蓝细菌和地衣杏仁虫。首先引入岩石相似性指数（RSI），然后应用于1659岩石系外行星。 RSI代表了类似地球的行星的量度，物理状况可能适用于可以在类似地球的极端栖息地（即热沙漠和寒冷的，冷冻土地）中生存的岩石极端粒子。
The search for different life forms elsewhere in the universe is a fascinating area of research in astrophysics and astrobiology. Currently, according to the NASA Exoplanet Archive database, 3876 exoplanets have been discovered. The Earth Similarity Index (ESI) is defined as the geometric mean of radius, density, escape velocity, and surface temperature and ranges from 0 (dissimilar to Earth) to 1 (similar to Earth). The ESI was created to index exoplanets on the basis of their similarity to Earth. In this paper, we examined rocky exoplanets whose physical conditions are potentially suitable for the survival of rock-dependent extremophiles, such as the cyanobacteria Chroococcidiopsis and the lichen Acarospora. The Rock Similarity Index (RSI) is first introduced and then applied to 1659 rocky exoplanets. The RSI represents a measure for Earth-like planets on which physical conditions are potentially suitable for rocky extremophiles that can survive in Earth-like extreme habitats (i.e., hot deserts and cold, frozen lands).
