Astronomers suspect that a massive metallic cloud swirling in a nearby star system could be hiding a giant planet or dwarf star from view, after it drastically dimmed a sun-like star for around nine ...

In theory, it could happen – one of the very first solutions to the three-body problem was this scenario. But it is very unlikely to be stable over time. You need the stars to have near equal mass and ...
