Two suns revolve around each other... the discovery of two rare binary star systems
An international team has identified a rare type of star system; It consists of two central stars orbiting each other, surrounded by a brilliant disk of gas and dust.
“If there was a planet in one of these systems, it would be like Tatooine from Star Wars, and you would see two suns in the sky orbiting each other, as well as That is, there is a disk around the stars, similar to the rings of Saturn but much larger, with the stars in the middle."
These disks are referred to as protoplanetary disks because they eventually form in families of planets such as our solar system, and newly discovered systems are rare because their disks lie at an angle with the orbits of their central stars.
“Planets are born from these disks, so having disks around binary stars shows that we are likely to find more planets orbiting binaries,” says John Zanacki, a postdoctoral fellow at the Canadian Institute of Theoretical Astrophysics and one of the study co-authors.
"It will also help to understand whether life can exist on a planet orbiting a binary star at an angle because of how that direction affects temperature and other conditions," he adds.
The discovery of the new bodies, called Bernhard-1 and Bernhard-2, was described in a paper published July 4 in the Astrophysical Journal Letters.
"Bernhard-1 and Bernhard-2 are too far away, and we can't see their central stars individually (these pairs of stars are known as binary stars). Instead, we see Just a single light point and we measure the total brightness of the diode."
