Maths up the Khyber
Now I am no astronomer, but I do know that if one object has 6 solar masses and another has 4, then the heavier is certainly not orbiting the lighter. Throw in a second 6-solar-mass object and the 4-baby is just a bit of fluff. So how one of the bigger ones "orbited an invisible [smaller] companion" needs some explaining, as does the apparently total rubbish artist's impression.
In fact, as an example of the three-body problem, either this system is highly unstable or the mass estimates are way off.
