Sarah Sadavoy (primary) and Steven Stahler (secondary) of UC Berkeley have recently released data and a hypothesis suggesting that most if not all stars in the universe are born as a binary pair.
“The key here is that no one looked before in a systematic way at the relation of real young stars to the clouds that spawn them. Our work is a step forward in understanding both how binaries form and also the role that binaries play in early stellar evolution. We now believe that most stars, which are quite similar to our own sun, form as binaries. I think we have the strongest evidence to date for such an assertion.”
Our own star’s birth companion spun off into parts unknown early on in their life, the scientists say.
