I mean a straight comet-like tail that seem to start from a point 11 light days from the hot dwarf.
My lines are drawn 5° to East from South
I don't see how you can make any reasonable assumptions about the distance of this structure from the star. Or how you can assume that a faint bright point is a planet as opposed to a star or a dust clump.
about the distance
There is 0.25 ly interval for scale.
The plane of the dwarf, the companion star, the light-year large ring and supposed planets is at an angle, making the ring an ellipse 2 times compressed in one direction. Were the position of the supposed planet at 7 o'clock from the star we should multiply the 11 light days by 2 and get 22 light days; as it is, the distance is more like 17 light days.
a faint bright point
Am I clumsy with words. I don't mean we can see the supposed planet as any dot.
I mean just a cometary tail that may start at a planet.
Here I try to highlight that tail:
