Excellent panel.

This one indicates that the star syasem is a double double, with the eclipsing pair hosting a circumbinary star.

Tidal interactions will now force the red dwarf to merge with the primary, and simultaneously drive the planet out away from the pair in a circularising orbit. What is even more interesting is the fact that the planet orbits in the same plane as the eclipsing pair so the tidal drift will be measurable with time.

It may take a very long time for the 2 stars to merge, as they have a relatively wide orbit and long period.

Have a nice day: Ag
