Planet found orbiting 3 stars at once, with giant dust rings - Big Think

Move over, Tattooine, and instead feast your eyes on GW Orionis, where the largest dust rings ever seen settle an ancient exoplanet debate.
ALMA, in which ESO is a partner, and the SPHERE instrument on ESO's Very Large Telescope have imaged GW Orionis, a triple star system with a peculiar inner region. The new observations revealed that this object has a warped planet-forming disc with a misaligned ring. In particular, the SPHERE image (right panel) allowed astronomers to see, for the first time, the shadow that this ring casts on the rest of the disc. This helped them figure out the 3D shape of the ring and the overall disc. The left panel shows an artistic impression of the inner region of the disc, including the ring, which is based on the 3D shape reconstructed by the team. Credit: ESO/L. Calçada, Exeter/Kraus et al.
The video is obviously a 3D render but based on extremely accurate data which is why it looks so real. The further out image is real, the rest are data driven renders.
Long story short, this is the first time a trinary star system with a planet orbiting around it has ever been seen. It's just lucky that it's also one we can get really cool pictures of. The existence of the planet is somewhat controversial because it has to exist but cannot be found.
Normally when a star forms it will end up with an accretion disk of material orbiting it, and that is essentially the same here but because the accretion disk is orbiting a trinary star system instead of just one star, it ends up with this huge tilted wave that makes it look like something out of a sifi movie.
As I understand it the planet has not been found but it has to exist based on the orbits. Presumably they can detect the effects of it's gravity.
