May 18, 2022 at 11:15 comment added ProfRob Question title is a duplicate of astronomy.stackexchange.com/questions/29902/… and should be edited. Only the part about transits vs eclipses is new. The general question of whether exoplants can be bigger than stars is addressed in astronomy.stackexchange.com/questions/47226/…

May 17, 2022 at 14:57 comment added Abhik Dutta The problem is that, when the exoplanet becomes as large as the star they are orbiting, they start orbiting each other. Because, since there mass becomes equal(Obviously if density is same) their total center of mass comes in their middle.
May 16, 2022 at 13:49 comment added FluidCode The problem seems to be more in the interpretation of the article. But for what matters the title, if the planet were so big it would probably be enough to start the fusion of its matter and become a star. So the system would be a binary star. A system were the star is small, just over the threshold for a fusion might exist, but difficult to see and if someone ever saw it a small intermittent star would have been a notable observation.
