binary system

In close binary systems, this expansion is so dramatic that the dying star's outer layers can sometimes completely engulf its companion.

We did not know we would find giant planets forming without parents stars at all, much less that we would see giant stars forming in pairs or binary systems with no stars at all.

Nemo’s powerhouse number “The Code” is about struggling to find their place and discovering it “somewhere between the zeroes and ones” of a binary system.

Researchers hope to apply their new aging method to other binary systems where dynamics have been well characterized, even without close flybys.

For over a decade, scientists have theorized that approximately one in three massive stars are stripped of their hydrogen envelope in binary systems.
