A birth-death-migration model for life in astrophysical environments

ABSTRACT To assess the number of life-bearing worlds in astrophysical environments, it is necessary to take intertwined processes abiogenesis (birth), extinction (death), and transfer life (migration) into account. We construct a mathematical model that incorporates this trio mechanisms accordingly derive probability distribution function other statistical properties (e.g. mean) for with biospheres. show given setting may become eventually saturated if rate successful transfers organisms higher than Based on available data, we suggest criterion might be fulfilled star-forming clusters (and perhaps Galactic bulge under optimal circumstances), thereby indicating such regions could constitute promising abodes hosting detecting life.
