Extremophile Life-form Survey on Rocky Exoplanets
Search for different life-forms elsewhere is the fascinating area of research in astrophysics and astrobiology. Nearly 3500 exoplanets are discovered according to NASA exoplanet archive database.
Earth Similarity Index (ESI) is defined as the geometrical mean of radius, density, escape velocity and surface temperature, ranging from 0 (dissimilar to Earth) to 1(Earth). In this research, rocky exoplanets that are suitable for rock dependent extremophiles, such as: Chroococcidiopsis and Acarosporamto, which can survive are considered. By calculating the weight exponential change in surface temperature parameter of ESI, the Colonizing Similarity Index (CSI) is introduced and analysed for 1650 rocky exoplanets.
