The discovery of a young planet explained the origin of the planetary system

Astrophysicists have discovered a young planet located 150 light-years from Earth. Her discovery

shed light on the planetary formation mechanismsystem. The planet DS Tuc Ab, which rotates around the star in a binary system, was formed without the strong influence of the gravitational attraction of the second star.

“We expected the thrust of the second star to tilta rotating disk of gas and dust that once surrounded the main star, that is, a process will occur that distorts the planet’s orbit, ”says Dr. Benjamin Montett, a researcher at the University of New South Wales. “But we did not find any evidence that the orbit of the planet was affected by this.” We also found that the planet was formed as a result of relatively quiet processes - which means that planets like Earth can survive in binary systems like this. ”

Dr. Montett worked with an international groupResearchers using Magellan telescopes located at the Las Campanas Observatory in Chile. They used the Planet Finder spectrograph to measure the Rossiter-McLaughlin effect, which is the relative angle between the planet’s orbit and the axis of rotation of its star.

They found that the planet DS Tuc Ab rotatesaround its star at approximately an angle of 12 degrees from the axis. This slight inclination indicates that the thrust from the companion star did not substantially incline the orbit of the protoplanetary disk where DS Tuc Ab was formed. While planets in the solar system have a slight slope, for planets like DS Tuc Ab, this is unusual.

“Most of these planets revolve aroundof his star at random angles, sometimes reaching 90 degrees with the axis of their star, says Dr. Montett. “The DS Tuc system is the first evidence that higher orbital angles are not detected at the beginning of a star’s life, they are most likely an effect that occurs later.”

The open planet is now only 40 million years old. So far, astrophysicists are aware of less than ten such planets that are considered young in the planetary dimension.
