I wonder if Walter Cruttenden still has the same view?
It would seem so, judging from the BRI webpage. At first, the candidate for a dual star seemed to be a brown dwarf (or a black hole), the limitation being that the distance of the stars in this binary system had to be pretty small.
Then it became Sirius after the research of the Australian astronomer on the possible higher velocity of the sun was published, which allowed for a greater distance.
I wonder if we could have a binary like Sirius yet at the same time both systems rotating closer and further from Alcyone. Would that be trinary? The two stars would not necessarily be orbiting a star like Alcyone but rather moving closer and further from it. Somebody must have thought of that possibility before me.
