[Lex Computer & Tech Group/LCTG] Astronomers may have discovered first planet to orbit 3 stars

[Tony]

George,

Looking at the star system image on the left, I think I am looking at a 
"point source" surrounded by 1 ~circular ring and 2 ~elliptical rings, 
all 3 geometrically "centered" at the 3-star group (1 bright, 2 
faint/invisible that did not ignite?). And, I am speculating that the 
point source comprises 1 live star and 2 invisible companions (that 
never ignited?) in stable orbit around each other (for a 3-body system).

In response to your question (re 4-body system), I think that if the 
planet is (and the rings are) "_/*_/*enough */_far away*/_" from the 
3-star group, then they sense essentially _/*a single circularly 
symmetrical gravitational well*/_, which would result in stable 
circular/elliptical planet orbit and dust rings.

I am saying circular/elliptical even though I think they are all 
circular (in far field), with the angular momentum vector of the inner 
ring pointing at a different direction than those of the planet (cleared 
path) and 2 outer rings that appear to be parallel to each other.

However, I am not an astrophysicist, so my speculation could be anywhere.

Cheers,

Tony
