A Star Is Born

Illustration of the ambipolar vortex in the protostellar core L1544. The blue lines represent the magnetic field; the red dots are ions and the green dots are neutral molecules. In the inner part of the core, the neutral molecules partially detach from the field and fall towards the center at a higher speed than the ions.

The cosmic "slip" that allows a star to begin being born has been measured

  • No comments
Magnetic fields can delay the collapse of clouds of gas and dust and delay the birth of stars. Using the 30-meter IRAM radio telescope, researchers measured a difference of about 50 meters per second between

Magnetic fields may explain how binary star systems form

  • No comments
Supercomputer simulations show that magnetic fields can subtract angular momentum from gas surrounding pairs of protostars, bringing them closer together and allowing the formation of a stable binary system. A similar mechanism may

The difference between the speed of dark matter and that of normal matter (baryons - all matter consisting mainly of hydrogen and helium). The speed difference is small in the areas marked in blue and large in the red areas. Compared to the density picture, the velocity shows a consistent structure on a much larger scale. Regions where the velocity differences are large are places where there are fewer stars because the halo is moving fast and is not trapped by the gravity of the dark matter concentrations, where the halo must accumulate to form stars.
