Galactica > Star formation

Summary

This project treats the evolution of molecular clouds (size of 100-200 pc) under self-gravity and MHD turbulence (see Ntormousi & Hennebelle, A&A, 2019 for a complete description). The elongated cloud has an initial mass of about 10^5 Ms. A turbulent field is initially set within the cloud. The adaptive mesh refinement scheme is employed to resolve scales up to about 100 AU. When a density of about 10^8 cm^-3 is reached, a sink particle is introduced. No stellar feedback is treated here and the turbulence is free to decay.

This project provides images of column density, density, temperature and magnetic field. Distribution of mass, density, temperature and magnetic field are given. Cores have been extracted using the HOP algorithm and their statistical properties (such as mass, internal velocity dispersion, size...) can be obtained. The corresponding statistics are also available. It is possible to query the clumps by specifying some requested properties. Finally the full clump data can be extracted and downloaded on demand.
