Re: Interesting stuff
Lucky you if you're in south !
Geez, sometimes I wish I had taken this doctoral thesis in stellar dynamics, several decades ago ...
Back then, black holes were purely hypothetical. And today, not only do we know there's one more or less in the center of every galaxy, but also one we can observe (not directly of course) without any tooling ! Which is right next door !
As for observation, you could probably pin point the movement of the 2 stars day after day during one month, by taking a pic with a telescope each day and see the rotation around "it".
But you would need to correct it by the rotation of the 2 stars set caused by their elevation vs. the solar plane and the trajectory of earth. Looks like Euler trigonometry is in order :)
