‘Upside-down planet’ reveals new method for studying binary star systems

What looked at first like a sort of upside-down planet has instead revealed a new method for studying binary star systems, discovered by a University of Washington student astronomer.

New studies boost binary-star formation theory

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 has a five-minute orbit

An international team of astronomers has discovered a weird pair of stars which orbit around each other in just five and a half minutes.
