An international research team led by Dutch astronomers at Leiden University discovered a young planet around the binary star system CS Cha. By studying the double star, the scientists accidentally discovered the image of this new planet.
According to astronomers, this planet is still being formed. On the other hand, the planet already has its own dust disk.
Scientists were able to confirm the presence of this planet thanks to an infrared image of the CS Cha binary. By passing the image under special polarizing filters, the researchers were able to observe the exoplanets and dust around CS Cha very clearly.
This new planet was found around the double star. To study it better, the experts used SPHERE, the observation tool of the gigantic European telescope in Chile
The CS Cha star and the young planet are located six hundred light-years away from Earth in the southern constellation called Chamaleon. The researchers describe it as a star formation area. First, astronomers studied binary systems to investigate this type of formation of stars and dust disks.
They then discovered a small dot in the photos they had taken of the system. The scientists then looked in the archive of the telescope for old photos that show this point. They found two, an eleven-year-old photograph taken by the Very Large Telescope, and a 1
Thanks to these ancient photos, scientists were able to discover that this young planet always existed accompanied the double star. However, the researchers still do not know what this planet looks like, whether it's a big planet or a small dwarf and how it came into existence.
According to Christian Ginski, lead author of this study and researcher at Leiden Observatory, this new planet is characterized not only by its strong polarization, but also by its own dust disk surrounding it. This prevents scientists from estimating their mass.
However, scientists are considering using the international ALMA telescope on the Chajnantor plateau in the northern Andes in Chile to better observe the double star CS Cha and his young neighbor.
