Full details about our results and methods are in the paper, including lots of gory details about all the binary simulations I needed to run in order to derive our results!

And we have another new candidate binary discovery, S4-308, that is *just a little too faint* to obtain spectroscopic confirmation from current ground based telescopes. But JWST can get its spectrum, so hopefully we can confirm soon if it is indeed a binary star!

One of the binaries, S2-36, is a new discovery, only about 0.1 pc (0.3 ly) from the galactic center supermassive black hole! We've spectroscopically confirmed it for the first time. It’s pretty unique and interesting in its own right, and we hope to have some exciting details about its story soon!

The other super exciting result from this paper is that we confirm for the first time that the fraction of young stars in binaries drops as we get close to the central supermassive black hole! It’s something that’s been predicted by many dynamical models, but we can now confirm it with observations!

Some models predict if the disk is being heated (maybe from an active central black hole 😉), you end up with high binarity in the resulting stellar population! Our results support this scenario, but we need higher fidelity simulations and more precise future binary fraction measurements!

A leading idea of star formation at the center of the Galaxy is that young stars formed in over dense regions of an accretion disk that previously surrounded the supermassive black hole.

🧵, with some more details!
So why is a high binary fraction at the center of the galaxy interesting / useful? Binarity is a consequence of star formation, and explaining how the young stars we see at the center of the Galaxy formed next to the supermassive black hole is still an open challenge.
