Description
I will show how to use Gaia astrometry to indentify binaries and companions in Young Stars. I will exemplify the power of this technique with a few science cases, from newly identified protoplanets within protoplanetary disks to a reassesment of the multiplicity of the populations of circumbinary and transition disks. I will conclude looking forward to the upcoming Gaia DR4 and the revolution it will bring for multiplicity analyses, once all individual epochs are published.
