magnetic properties of star-forming dense cores

Magnetic fields in space are sometimes called the last piece in the puzzle of star formation.

They are much harder to measure than the masses or motions of star-forming clouds, and their strength is still uncertain.

If they are strong, they can deflect or even oppose gas flowing into a young stellar core as it collapses under the influence of gravity.

An image of the magnetized, star-forming core BHR 71 IRS1.

The outermost low- density gas is shown by the blue and white background colors; the centrally concentrated core gas is shown by the black contour lines and green color.

The central protostar and planet-forming disk are shown by the orange circle.

The associated magnetic field lines are shown by the curved white lines, whose shape indicates that the field has been pulled inward by the contracting dense gas .

Astronomers have completed the first analysis of magnetic field influences in star-forming cores using a combination of techniques.
