  1. 145. A grid of models for wind bow shocks from massive runaway stars
    Dominique Meyer

    Poster
    This poster presents a grid of models following the wind-ISM interaction of massive runaway stars from the main-sequence to the supernova stage. The included physics takes into account optically-thin radiative heating and cooling, together with electronic thermal conduction and assumes that the stars are moving in a medium which density corresponds to the one of the Galactic plan. Emissions...

    Poster
    The Scorpius-Centaurus OB association is the nearest region of recent massive star formation. With several distinct stellar groups ranging in age from a few to ~15 Myr, it presents an interesting labratory to explore the interaction between stellar feedback, the ISM, and the formation of clusters and associations from molecular clouds. An apparent age sequence along the association raises the...

  3. 39. Gas kinematics of supergiant shells in two nearby galaxies.

    Poster
    We present observations and analysis of two dwarf Irr galaxies in M81 group - IC 2574 and Holmberg II. Their 21 cm images of these galaxies show multiple shell-like structures with sizes up to 1-2 kpc, so-called supergiant shells (SGS), most probably created by stellar feedback from several generations of stars. According to modern understanding the SGS expansion triggers new bursts of star...

  4. 147. Molecular Cloud Evolution Under Varying Conditions - Formation Process and Stellar Feedback
    Mr Sebastian Körtgen

    Poster
    Authors: Bastian Körtgen, Daniel Seifried, and Robi Banerjee Affil: Hamburger Sternwarte, University of Hamburg, Gojenbergsweg 112, 21029 Hamburg, Germany Molecular clouds represent the birthplaces of stars. Their study is therefore essential to understand the formation of stars. In this study, we present two sets of simulations to analyse the formation and evolution of molecular clouds by...

  5. 136. Properties of protostellar outflows from IR-spectroscopy in NGC 1333
    Volker Weiss
    23/10/2013, 09:00
    Poster
    In order to help clarifying the role of protostellar jets and outflows as potential drivers for stirring the turbulence of molecular clouds, we assess physical parameters of outflows such as energy and momentum and combine near-infrared and radio data of well-investigated regions, use excitation models to account for missing transitions, and keep the time-variability of the flows as well as...
