A sun-like star orbiting a black hole.
The OJ 287 galaxy hosts one of the largest black holes ever found, with over 18 billion times the mass of our Sun. Orbiting this behemoth is another massive black hole. Twice every 12 years, the smaller black hole crashes through the enormous disk of gas surrounding its larger companion, creating a flash of light brighter than a trillion stars.
It was observations in the early 2000s of the closest stars orbiting Sgr A*, like the gravitationally redshifted star S2, that gave astronomers really convincing evidence that Sgr A* contains a supermassive black hole.

They estimate the star ...Then, the star needs to be sufficiently far away from the black hole, so the ringworld must be farther still. Which requires a somewhat larger star to achieve the same irradiance on the ringworld surface. Finally, gravity. A 1AU ringworld rotating around a G0 star like the Sun will have a "neutral" orbital speed of one rotation per year.

Jun 18, 2021 · 2. If you don't consider how the black hole (BH) has formed, then it is quite possible for a black hole to form a bound state with a massive object like a star. They can circle (or ellipse) around their center of mass (COM). If this COM lies close to the star then the BH will be orbiting around the star.

There are other ways to draw gas mass into the center, such as gas. Non-axisymmetric density patterns in galactic gas can lead to torques that draw gas into the center, and this may be part of the way that massive black holes grow.
