| Abstract: | We suggest a model for the star-formation function and the dissipation of turbulent energy of the interstellar medium. The star-formation function takes into account the effect of turbularization of the ISM. Applying the derived relations to a hierarchical scenario for the formation of galaxies makes it possible to explain the observed delay of star formation in the Galaxy, which corresponds to a range of stellar ages from 8–9 to 10–12 Gyr. |
