HTTP:: Stellar Formation and Magnetic Fields Strongly Linked
--------
According to scientists at the Harvard-Smithsonian Center for Astrophysics, it may be that magnetic fields play a much more important and decisive role in stellar formation than first anticipated. The conclusion was drawn after the experts made a comparative analysis of turbulences versus magnetic fields. The two phenomena were the ideal candidates to explain why stellar nurseries â€" areas of intense stellar formation â€" only produced small amounts of stars, at specific locations, as if something was hindering the growth process. The accepted knowledge on stellar formation at this point holds that stellar nurseries, which are, in essence, molecular clouds, filled with cosmic dust and gas, occasionally and under precise circumstances fall under their own gravitational pull into an area much smaller than their original size, and, as a result, ignite. However, if that alone were true, then all sections of known molecular clouds should have young, blue stars, whereas this is!
not the case. Therefore, other forces must be at work to prevent stars from appearing everywhere, and magnetic fields and turbulences have been the best bet. “The relative importance of magnetic fields versus turbulence is a matter of much debate. Our findings serve as the first observational constraint on this is...
