Moreover at small scales, magnetic braking is likely a dominant Influence remains to be better understood. Reducing the star formation rate in dense molecular cloud gas by a factor of aįew, ii) strongly shaping the interstellar gas by generating a lot of filamentsĪnd reducing the numbers of clumps, cores and stars, although its exact Have been measured, it is likely that magnetic field is i) responsible of We argue that given the magnetic intensities that Finally we briefly review its possible effects on the formation of On the prestellar dense cores as well as regarding the formation of stellarĬlusters. Then the influence that magnetic field may have on the interstellarįilaments and the molecular clouds is discussed, notably the role it may have What is known regarding the correlation between the magnetic and the densityįields. Turbulence, thought to play a fundamental role in the ISM. Then we discuss our current knowledge of compressible magnetized Medium (ISM) and the thermal processes that allows this gas to become denserĪre presented. The nature of the multi-phase interstellar Leading to ideal MHD equations, their most important correction, namely the After a brief presentation and main assumptions Download a PDF of the paper titled The role of magnetic field in molecular cloud formation and evolution, by Patrick Hennebelle and Shu-ichiro Inutsuka Download PDF Abstract: We review the role that magnetic field may have on the formation andĮvolution of molecular clouds.
