16. In 2022, researchers used high angular resolution techniques to show that the two stars are actually much closer (angular separation of 1.2 mas) than the 100 mas previously expected. Using Kepler's Third Law, explain why the smaller diameter orbit (still with P-40.3 days), could be caused by less total mass, eliminating the need for the presumed black hole.
