Physical properties of the quadruple system with early-type eclipsing binary
An early-type eclipsing binary turns out to be a hierarchical quadruple system. Analysis of its complex configuration, although not easy, yields masses, radii, and temperatures of the inner binary, and mass estimations of the two outermost components.
Was it a bird..? Was it a plane..?
It was… Falcon 9 😉
