The study of molecular clouds has shown that stellar formation takes place in two stages. First, supersonic flows squeeze the clouds into dense threads, after which gravity destroys them into nuclei. Massive ones arise at the intersection points of the filaments, forming regions of the grouped stellar birth.
All this seems logical, but the observed in reality the rate of birth of stars in dense gas is only a certain percentage of the expected. To deal with the problem, scientists have suggested that magnetic fields keep the nuclei from collapsing. Magnetic fields do not want to be calculated or interpreted. Therefore, the researchers used a submillimeter array to view the 6 dense nuclei located in the territory of Cygnus. They calculated the field strength during polarization, and then compared the field directivity in the cores with the direction along the filament.
It turns out that the field along the thread is perfectly ordered and stands parallel to the structure. That is, when creating nuclei, the magnetic fields lose their weight in comparison with turbulence and inflation.
