(http://wwwcdn.skyandtelescope.com/wp-content/uploads/Dusty-Disk-BHB07-11-600px.jpg) (http://wwwcdn.skyandtelescope.com/wp-content/uploads/Molecular-outflow-1200px.jpg) (http://wwwcdn.skyandtelescope.com/wp-content/uploads/Molecular-outflow-1200px.jpg) (http://wwwcdn.skyandtelescope.com/wp-content/uploads/Magnetocentrifugal-wind.png) The magnetocentrifugal force has long been thought to power outflows from young stellar disks. However, while the classical picture has the magnetic field pinching into an hourglass shape within the disk (pictured here), the ALMA observations of BHB07-11 show that the pinching action may actually occur at or just outside the disk's edge.
