    • The accumulation and trapping of grains at planet gaps: Effects of grain growth and fragmentation 
      González, J. F.; Laibe, G.; Maddison, S. T.; Pinte, Christophe; Ménard, Francois (Elsevier, 2015)
      We model the dust evolution in protoplanetary disks with full 3D, Smoothed Particle Hydrodynamics (SPH), two-phase (gas+ dust) hydrodynamical simulations. The gas+ dust dynamics, where aerodynamic drag leads to the vertical ...
    • ALMA images of discs: are all gaps carved by planets? 
      González, J. -F.; Laibe, G.; Maddison, S. T.; Pinte, Christophe; Ménard, Francois (Oxford Univ Press, 2015)
      Protoplanetary discs are now routinely observed and exoplanets, after the numerous indirect discoveries, are starting to be directly imaged. To better understand the planet formation process, the next step is the detection ...
    • Compact Dust Concentration in the MWC 758 Protoplanetary Disk 
      Marino Estay, Sebastián; Casassus Montero, Simón; Perez, Sebastián; Lyra, W.; Roman, P.; Avenhaus, H.; Wright, C. M.; Maddison, S. T. (The American Astronomical Society, 2015-11-01)
      The formation of planetesimals requires that primordial dust grains grow from micron- to kilometer-sized bodies. Dust traps caused by gas pressure maxima have been proposed as regions where grains can concentrate and ...
    • Compact dust concentration in the mwc 758 protoplanetary disk 
      Marino Estay, Sebastián; Casassus Montero, Simón; Pérez, Sebastián; Lyra, W.; Román, P.; Avenhaus, H.; Wright, C. M.; Maddison, S. T. (IOP Publishing, 2015)
      The formation of planetesimals requires that primordial dust grains grow from micron- to km-sized bodies. Dust traps caused by gas pressure maxima have been proposed as regions where grains can concentrate and grow fast ...
    • Resolving structure of the disc around HD100546 at 7 mm with ATCA 
      Wright, C. M.; Maddison, S. T.; Wilner, D. J.; Burton, M. G.; Lommen, D.; Dishoeck, E. F. van; Pinilla, P.; Bourke, T. L.; Ménard, Francois; Walsh, C. (Royal Astronomical Society, 2015)
      There is much evidence that planet formation is occurring in the disc around the Herbig Be star HD100546. To learn more about the processes occurring in this disc, we conducted high-resolution imaging at 43/45 GHz with the ...
