ATTRACTIVE PAIR  Magnetic stars (illustrated) could help create massive black holes. This is a visualization of a pair of such stars discovered in 2015. Yellow lines trace the magnetic field, and color shows north (red) and south (blue) magnetic poles.

To create a heavy black hole, it might help to start with a massive magnetic star.

Strong magnetic fields could help stem the flow of gas from a heavyweight star, leaving behind enough material to form hefty black holes, a new study suggests. A pair of such magnetic stars could be responsible for giving birth to the black hole duo that created recently detected gravitational waves, researchers report online December 1 in Monthly Notices of the Royal Astronomical Society.
