J1407 star system

1SWASP J140747.93−394542.6 (also known as J1407 and Mamajek's Object) is a star similar to the Sun in the constellation Centaurus at a distance of about 434 light-years from Earth. A relatively young star, its age is estimated to be 16 million years, and its mass is about 90% that of the Sun. The star has an apparent magnitude of 12.3 and requires a telescope to be seen. The star's name comes from the SuperWASP (Wide Angle Search for Planets) program and the star's coordinates. The star is variable due to the planet orbiting around it and has been given the variable star designation V1400 Centauri.
In 2007, J1407 was observed to be eclipsed and orbited by at least one major body, J1407b, thought to be either a large gas giant planet or a brown dwarf, with an immense ring system. Subsequent observations have not successfully detected J1407b, suggesting that it is on a highly eccentric orbit around the star.
By 2021, it was discovered the parent star is strongly variable, with a 5.4-year long magnetic activity cycle, and no evidence was detected of additional planets or a repeat of the deep eclipses attributed to a transiting ring system.

To keep a stable ring system I decided to make orbit 2x further away that where astronomers think it is and the orbit is also not eccentric for the same reason.

I also added some moons aroun the planet to simulate the formation of moons in ring system + we have found gaps between rings
