The Origin of Massive Stars: The Inertial-Inflow Model
Paolo Padoan, Liubin Pan, Mika Juvela +2
We address the problem of the origin of massive stars, namely the origin, path and timescale of the mass flows that create them. Based on extensive numerical simulations, we propos…
The CARMA-NRO Orion Survey: Core Emergence and Kinematics in the Orion A Cloud
Shuo Kong, Héctor G. Arce, Anneila I. Sargent +19
We have investigated the formation and kinematics of sub-mm continuum cores in the Orion A molecular cloud. A comparison between sub-mm continuum and near infrared extinction shows…
Synthetic observations of dust emission and polarisation of Galactic cold clumps
Mika Juvela, Paolo Padoan, Isabelle Ristorcelli +1
The Planck Catalogue of Galactic Cold Clumps (PGCC) contains over 13000 sources detected based on their cold dust signature. They are believed to consist of a mixture of quiescent,…
The Probability Distribution of Density Fluctuations in Supersonic Turbulence
Liubin Pan, Paolo Padoan, Åke Nordlund
We study density fluctuations in supersonic turbulence using both theoretical methods and numerical simulations. A theoretical formulation is developed for the probability distribu…
Inaccuracy of Spatial Derivatives in Simulations of Supersonic Turbulence
Liubin Pan, Paolo Padoan, Åke Nordlund
We examine the accuracy of spatial derivatives computed from numerical simulations of supersonic turbulence. Two sets of simulations, carried out using a finite-volume code that ev…
The CARMA-NRO Orion Survey: The filamentary structure as seen in CO emission
S. T. Suri, A. Sanchez-Monge, P. Schilke +18
We present an initial overview of the filamentary structure in the Orion A molecular cloud utilizing a high angular and velocity resolution CO(1-0) emission map that was rec…
