Although planetary disks were discovered a long time ago, these disks are considered the first building blocks for the formation of huge planets such as Earth and other planets of the olfactory group.
Scientists believed for a very long time that the planets are formed due to the protoplanetary disks that revolve around the stars, but they pointed out that the moons have another origin, for example, but not limited to, and were considered a separate part of the mother planet.
The discovery of the first lunar disk changes beliefs
Astronomers have observed, for the first time, a planetary disk wrapping around a planet called “GQ Lupi B” orbiting its parent star on a path about 20 times greater than the path of Jupiter around the sun.
According to the article published in the “scitechdaily” magazine, this discovery helped build a new theory that moons are also formed from planetary disks, not just planets.
The research was carried out by a group of scientists led by Dr. Thomas Stolker, from the University of “Leiden”, who delved into the study of the planet and investigated the properties of the “proto-lunar disk” that surrounds the planet “GQ Lupi B” outside the solar system, which he called “super Jupiter.” About 500 light-years away.
A growing planet is hollow inside
Stolker’s team collected data using a very large telescope, infrared images, and a visible-light spectrometer.
The team monitored the thermal appearance of the disk surrounding the planet, which is a lunar disk with a temperature much lower than the planet’s atmosphere, which led researchers to believe that there was a “cavity” in the ring where the moon began to coalesce.
Using alpha rays, the researchers were able to detect the features of the planet’s atmosphere, and note that the planet was still in a developing stage, using either a supply of material it obtained from its protoplanetary disk or grabbing material from the protoplanetary disk of its star.
