  1. 17. The structure of molecular clouds from 1000 AU to Orion
    Joao Alves (University of Vienna)
    21/10/2013, 12:05
    review talk
    Understanding how matter is organized inside a molecular cloud is key to understand where and how stars form. In this talk we summarize the main results from our ongoing program on NIR extinction on nearby molecular clouds, complemented with recent Herschel archival data. Our sample comprises all the nearby molecular cloud complexes in their entirety, from Pipe Nebula to the Orion complex,...

  3. 21. Properties of interstellar filaments observed with Herschel and 3D magnetic field structure derived from the polarization parameters observed with Planck
    Doris Arzoumanian (IAS Orsay)

    contributed talk
    Herschel dust continuum images have revealed the ubiquity of filaments in the interstellar medium (ISM) and their fundamental role in the star formation process. Planck dust polarization observations trace the magnetic field structure of the ISM. Filamentary structures are formed by the interplay of interstellar turbulence, gravity and magnetic field. What is the role of these various...

  4. 24. Magnetic Fields in Bok globules
    Gesa Bertrang (ITAP, University of Kiel)

    contributed talk
    The influence of magnetic fields on the star-forming process is still under debate. A very good environment to study this influence is given in low-mass star-forming regions, so-called Bok globules. These objects are less affected by other processes, such as large-scale turbulences. The magnetic field strength and structure in the dense inner regions of these globules can be determined by...

  5. 60. Effect of turbulence on the density statistics of molecular clouds: an observational view
    Jouni Kainulainen (Max-Planck-Institute for Astronomy)
    21/10/2013, 15:00
    contributed talk
    Supersonic turbulence has a profound impact on the density structure of the cold interstellar medium (ISM). Consequently, observations of the ISM density structure can be used to constrain the fundamental properties of turbulence. However in practice, connecting the observed density structure to theoretical predictions is greatly hampered by the inability of observations to probe the wide...

  6. 97. Filamentary Structures in the ISM
    Rowan Smith (ZAH/ITA University of Heidelberg)
    21/10/2013, 15:15
    contributed talk
    Filaments are seen throughout the ISM, from long filamentary IRDCs to individual filamentary sites of star formation. Using the moving mesh code AREPO we can investigate filament formation on all scales, as  the unique combination of a Lagrangian mesh with a Riemann solver results in an extremely accurate treatment of shocks and discontinuities. I will describe how filamentary molecular clouds...
