Semianalytic models are currently the best way to understand the formation of galaxies and clusters within the cosmic web dark matter gravitational skeleton. We study the shape and evolution of the star formation main sequence in three independently developed semianalytic models of. By coupling semianalytic models of galaxy formation to a recipe that relates the occurrence of planets to the mass and metallicity of their host stars, we trace the population of terrestrial. The galacticus model was designed to be highly modular to facilitate expansi.
