What Shapes the Structure of Molecular Clouds: Turbulence or Gravity?
Alexei G. Kritsuk, Michael L. Norman
We revisit the origin of Larson's scaling relations, which describe the structure and kinematics of molecular clouds, based on recent observations and large-scale simulations of su…
Turbulent Clustering of Protoplanetary Dust and Planetesimal Formation
Liubin Pan, Paolo Padoan, John Scalo +2
We study clustering of inertial particles in turbulent flows and discuss its applications to dust particles in protoplanetary disks. Using numerical simulations, we compute the rad…
Comparing Numerical Methods for Isothermal Magnetized Supersonic Turbulence
Alexei G. Kritsuk, Aake Nordlund, David Collins +13
We employ simulations of supersonic super-Alfvenic turbulence decay as a benchmark test problem to assess and compare the performance of nine astrophysical MHD methods actively use…
