The start of the birth of planets in a binary star system observed
13 April 2022
In space unexpected detail, astronomers have discovered primordial material that may be giving birth to three planetary systems around a binary star. An international team of scientists has seen a pair of stars orbiting each other, revealing that they are surrounded by gas and dust disks, based on three decades of research. The material found in the newly discovered disks could be the start of new planet systems space that will circle binary stars in the future.
Formatting models of planets
Planet formation models suggest that planets form via the gradual accumulation of ice and dust particles in protoplanetary disks encircling young stars. These models only consider single stars, such as the Sun, in most cases. On the other hand, the majority of stars form binary systems, in which two stars rotate around a common center. Little is known about how planets develop in these important twin star systems, where the gravitational interaction between the two stars is crucial.
- Our findings suggest that each star is surrounded by a gas and dust disk and that a larger disk is forming around both of them. This outer disk depicts a spiral structure that feeds matter into the individual disks, and planetary systems may form in the future in all of them. This is strong evidence for disks encircling both stars and the existence of a shared disk in a binary system. \s” This outer disk depicts a spiral structure that feeds matter into the individual disks, and planetary systems may form in the future in all of them.

Why assumed that binary system
The binary system SVS 13, which consists of two stellar embryos with a total mass similar to the Sun, is quite close to us in the Perseus molecular cloud, around 980 light-years away, permitting careful investigation. The system’s two stars are extremely close, with a distance of just around ninety times that of the Earth and the Sun.
SVS 13 has sparked great disagreement in the scientific community, with some studies claiming it to be very early and others claiming it to be in an advanced stage. This new study, which is likely the most comprehensive examination of a binary star system in formation, provides critical parameters for testing numerical simulations of binary and multiple system formation in the early stages and sheds light on the nature of the two proto stars and their surroundings.
