The initial team and one of the follow-up teams have teamed up to examine HR 6819 with more powerful telescopes, gathering a different kind of data. The new measurements may reveal finer details in the sky, allowing astronomers to see things that they couldn’t before. to definitively see how many objects are in the system and what type of objects they are, the teams report in the March Astronomy & Astrophysics.

“Ultimately, it was the binary system that best explains everything,” says astronomer Abigail Frost of KU Leuven in Belgium.

Because previous observations of HR 6819 revealed it as a whole, astronomers could not tell the components in the system apart or their masses. To figure out HR 6819’s actual nature, Frost and his colleagues utilized the Very Large Telescope Array, which is made up of four telescopes in Chile that may really see the individual stars.
