Following up on this story, ten years later; the 'very large ring system' hypothesis doesn't look realistic any more, and it might instead be some sort of free-floating disk or object that passed by the star by coincidence.

In some ways it is a good thing that we did not include this object, (IIRC).

Quote:While the properties of the ALMA object appear to match those of J1407b, it has only been observed once, making it uncertain whether its motion aligns with the expected direction and speed.[1]: 5 It is possible that the ALMA object could be a stationary background galaxy or a spurious detection caused by image noise, although these two possibilities are considered unlikely.[1]: 5 ALMA reobserved V1400 Centauri in June and July 2024, which may provide insight into the object's nature once the data is analyzed and published.
