Unlike the majority of exoplanets discovered through indirect means, the planets that we find through imaging may be followed up with spectroscopy of their gaseous atmospheric content and astrometric monitoring of their orbital properties — both of which provide important clues to how and where they formed in their natal circumstellar / circumbinary disks.

We're being surprised over and over again: circumbinary planets, which orbit two stars instead of one, for example, or compact multi-planet systems.

The worlds are aptly named «circumbinary planets» («circum» meaning around, and «binary» referring to two objects), and in this type of binary system, the two stars orbit each other while the planet orbits the two stars (pictured above).

Now, astronomers have asked a new question: What would happen if a circumbinary planet were in the mix?

The researchers mathematically showed that the same mechanism that forces the binary together shifts the alignment of the circumbinary planet, potentially allowing it to sneak far enough away to escape incineration.
