    To date, numerical studies of the IMF have adopted initial conditions that are very dense -- often comparable to the densities of individual prestellar cores that are observed in giant molecular clouds (GMCs). These calculations, which start in the regime where the gas and dust are already strongly coupled, can say nothing about conditions we observe in nearby star-forming regions. In...

  4. 22. Photoionization of the diffuse ionised gas in an MHD supernova-driven turbulent Interstellar Medium

    We investigate 3D photoionisation models of the Diffuse Ionised Gas (DIG). Our simulations show that in a supernova-driven, turbulent magnetised medium photons from OB stars in the Galactic plane are able to travel many kiloparsecs and reach heights required to ionise the DIG. To reach these heights photons travel through ?bubbles? evacuated by supernovae close to the midplane of the...

  5. 143. The molecular richness of diffuse ISM: a tracer of turbulent dissipation
    Prof. Edith Falgarone (LERMA/LRA Ecole Normale Supérieure)
    21/10/2013, 17:30
    The diffuse interstellar medium has long been known to harbor a remarkable molecular richness, that cannot be understood in the framework of state-of-the-art UV-driven chemistry. Absorption spectroscopy performed with Herschel/HIFI reveals unexpected large abundances of small hydrides that are the building blocks of interstellar chemistry in the diffuse medium. Because they are so abundant...
