A very exciting paper by Kral et al. on “Exomoon search with VLTI/GRAVITY around the substellar companion HD 206893 B” using astrometric measurements of the companion to search for a putative #exomoon. Half a Jupiter mass at 0.22 au maaaaybe? We’re getting closer! #astrodon #astrosci #exoplanets

A cartoon showing the star with two planets orbiting it. The outer planet/BD has a putative moon orbiting it, and there are two dust belts further out in the system.a set of orbital fits to the residuals from the astrometric fit. They look like a set of drunk hula hoops piled on top of each other, but definitely hinting at a signal in there.
