SKA-VLBI is projected to deliver an order-of-magnitude gain in astrometric precision, enabling detection of thousands of exoplanets around ultra-cool dwarfs, M dwarfs and young stars plus dynamical masses when companions are also imaged.

abstract
The discovery and subsequent detailed study of T dwarfs has provided many surprises and pushed the physics and modeling of cool atmospheres in unpredicted directions. Distance is a critical parameter for studies of these objects to determine intrinsic luminosities, test binarity and measure their motion in the Galaxy. We describe a new observational program to determine distances across the full range of T dwarf sub-types using the NTT/SOFI telescope/instrument combination. We present preliminary results for ten objects, five of which represent new distances.

Ultra-Precise Astrometric Search for Exoplanets with SKA-VLBI
SKA-VLBI is projected to deliver an order-of-magnitude gain in astrometric precision, enabling detection of thousands of exoplanets around ultra-cool dwarfs, M dwarfs and young stars plus dynamical masses when companions are also imaged.
