Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth.

Precession-driven fluid dynamics concerns the intricate motions arising when a rotating body experiences a slow, conical motion of its spin axis, a phenomenon that is pivotal in both geophysical and ...
