Astrometric follow-up observations of directly imaged sub-stellar companions to young stars and brown dwarfs

C. Ginski, T. O. B. Schmidt, M. Mugrauer +4

The formation of massive planetary or brown dwarf companions at large projected separations from their host star is not yet well understood. In order to put constraints on formatio…
