"Dynamics of Disc-Binary Systems"

Abstract

Half of all stars are part of a binary or multiple system, many of which will form together within one circumbinary disc.

The forming stars and disc interact reshaping the disc and the orbits of the binary pair. In this talk, we will look at these effect

with the help of 2D hydrodynamic simulations.We will investigate the impact that the physical conditions in the disc have on

interaction and how the thermodynamics in the disc change the the disc-binary behaviour depending on separation of the binary stars.

This allows us to understand the circumbinary disc structure we can observe with ALMA.
