We present some preliminary results obtained with a new galactic chemodynamical tool under development. In the framework of non-instantaneous recycling approach, we follow the interactions due to star formation and feedback processes. One of the main original features of our code is that we record the abundance evolution of several chemical elements. This allows us to build cooling functions dependent on the real abundances of individual elements. We illustrate the need for such metal-dependent cooling functions using a toy model made of a star cluster embedded in a two-phase gas cloud. Our results suggest that computing cooling rates according to individual abundances of chemical elements can influence the star formation rate.

    ABSTRACT: The first numerical simulations of supernova remnant evolution in an inhomogeneous gas are presented. Evolution in the lowest density substrate (the intercloud) is assumed to be spherically symmetric with a large intercloud filling factor and many dense regions (clouds) within the remnant; however, mass momentum and energy transfer between cloud and intercloud are included and the position and morphology of individual clouds tracked. Evolution is considered in several different models of the interstellar medium, both those in which the intercloud gas is diffuse (0.001 to 0.01/cu cm) and those in which it is relatively dense (n approximately 0.3/cu cm) under a variety of assumptions about the efficiency of thermal evaporation from the clouds into the intercloud medium.

    ABSTRACT: The cooling functions for a plasma slab are investigated under equilibrium and nonequilibrium conditions, over a range of 10 exp 4 - 10 exp 8.5 K and for a range of abundances. Radiative transfer and diffuse field are calculated in the isobaric nonequilibrium models using a one-dimensional cooling flow model, and the plasma is not assumed to be optically thin to all radiation. Limiting cases of the plasma diffuse field coupling are calculated, and the resulting cooling functions are presented. Some functions are terminated before reaching 10 exp 4 K when the internal photoionization halts the cooling. The functions represent a self-consistent set of curves covering a wide grid of temperature and metallicities using recently published atomic data and processes. The results have implications for phenomena such as cooling flows and for hydrodynamic modeling which include gas components.
