Exoplanet Discovered in Unique Polar Circumbinary Disc

Astronomers have discovered evidence of an exoplanet in a polar circumbinary disk surrounding a binary star system, marking the first observation of its kind. The disk, located around the binary star AC Herculis, exhibits a large inner radius and a telltale gap indicating the presence of a planet. The primary star in the system is a post-AGB star, suggesting that the exoplanet may be a second-generation planet formed from the debris of destroyed first-generation planets. While the characteristics of the planet remain unknown, further study of this unique system is warranted.
