Protoplanetary disks don’t exist in isolation; when young stars pass each other by, their gravitational encounter can disrupt, or maybe even kickstart, planet formation.

Today’s paper posits that precise observations of wide binaries can be used, in conjunction with simulations, to test the validity of modified gravity theories!

In today’s paper: how does tidal dissipation and gravitational wave emission affect the result of encounters between stars and black hole binaries in stellar clusters?

We know that a cluster can be a dangerous place for a young star trying to form some new planets. Radiation and winds from massive stars can evaporate the planetary disc, and the gravitational pull from fly-bys of other stars can disrupt the disc and drag the planet-forming material away.

Steep density drop-offs and orbits with high inclinations and eccentricities are just a few of the mysterious features in the outer reaches of our Solar System – can a single stellar fly-by help explain all of them?

You can’t model RW Aurigae as a single star with a disk of material around it, because there is a second star. And you can’t model it as a regular old binary system either, because there are interactions between the stars and the asymmetric disk. The authors of today’s paper create a comprehensive hydrodynamic model that considers many different observations of RW Aurigae.
