A very young planet with two suns was discovered

Astronomers have found a huge planet (or a brown dwarf) near the young double star, which was formed, by space standards, more recently – no more than three million years ago. Perhaps it is still growing in mass, capturing matter from the surrounding disk of dust and gas.

A group of astrophysicists from several European countries and Chile published their observations of the young double star CS Cha in the constellation of Chameleon, around which a disk of dust and gas rotates and, probably, the process of forming planets.

The stars of the CS Cha system are only 2-3 million years old, and the cloud of matter, as a result of the collapse of which they ignited, has not yet fallen into dense pieces – planets and asteroids, and has not flown away. Quite recently a massive (about 20 mass of Jupiter) exoplanet was formed from it (perhaps even a substar object – a brown dwarf). The radius of its orbit is 200 times larger than the radius of the Earth’s orbit.

The head of the research team, Christian Ginsky of the Leiden Observatory, says: “The most noteworthy in all this is the high degree of polarization of light that reaches us from this object; she says that the light of stars, passing through the neighborhood of this body, is strongly dissipated. We assume that he is surrounded by his own disc of matter. However, because of this, it is difficult for us to estimate the mass of this object, so we do not know what it is: it could be a young super Jupiter or a brown dwarf. The classical models of planetary formation are useless here. ”

Further study of young exoplanets should help scientists create new models of the processes leading to their formation, and shed light on the history of our own planetary system.
