The planets were imaged using high-contrast, near-infrared adaptive optics observations with the Keck and Gemini telescopes. In a, Wang said he was instantly fascinated by the system when the news broke in 2008, and has been watching it ever since. He and his colleagues applied for time on the W. M. Keck Observatory, located on the top of Mauna Kea in Hawaii, to observe the system each year.
“There’s nothing to be gained scientifically from watching the orbiting systems in a time lapse video, but it helps others appreciate what we’re studying,” Wang said. “It can be difficult to explain the nuances of science with words. But showing science in action helps others understand its importance.”
The outer planet orbits inside a dusty disk, much like our own Kuiper belt. Astronomers says it is one of the most massive disks known around any star within 300 light years of Earth. There is an additional debris disk just inside the orbit of the innermost planet – which was the fourth planet to be found. Astronomers say that would be room in the inner system for terrestrial planets. The planet nearest the star takes about 45 Earth years to make one revolution.
