Abstract: Young stars affect their environment in many ways and one of the earliest effects is the heating of the dust and, indirectly, the gas by radiation. The heating of the gas will raise the Jeans Mass and affect nearby star formation, possibly inhibiting the growth of low mass-stars. We investigate this process in our SPH simulation, which includes gravity, particle splitting, sink particles, and a new technique for modeling dust and gas energetics. The dust and gas energetics are powered by the accretion luminosity of young stellar objects which heats the surrounding dust to high temperatures. At high densities, the hot dust heats the gas through collisions. At lower densities, the heated gas is able to cool via rotational molecular lines, primarily from CO. At very low densities, the gas may also be heated by cosmic rays. We consider these effects in our simulation of a clustered star-forming region. We discuss our methodology and preliminary results.
