A New Study of How Binary Stars Form

A New Study of How Binary Stars Form

  Using the new capabilities of the upgraded Karl G. Jansky Very Large Array (VLA), scientists have discovered previously-unseen binary companions to a pair of very young protostars. The discovery gives strong support for one of the competing explanations for how double-star systems form. Binary star formation through disk fragmentation starts (left) with a young [continue reading]
