An exoplanet with desire to death: Hip 67522 B shrinks in space!

Centaurus, Australien - The exoplanet HIP 67522 B discovers with the Swiss space telescope, represents a real mystery in the universe. A G-Type Stern circles in 415 light years away in the constellation Centaurus, is just 17 million years old and thus the youngest known planet of its kind.

hip 67522 B is classified as a "hot Jupiter". Its extreme closeness to his star means that he triggers huge sun -ups (flares) that are so strong that they harm the planet. These eruptions blow the atmosphere of hip 67522 B continuously, which means that it loses mass and size every year. Forecasts show that the planet could shrink to that of the Neptuns within the next 100 million years.

the proof of a "planet with the desire to death"

With hip 67522 B, a “planet with desire to death” was detected for the first time. The star itself, which the planet circles, is very energetic and shows a magnetic activity that is more than 100 times more energetic than expected. Researchers can help these properties to understand the process of creating other hot Jupiters. In addition, the density of hip 67522 B, which is below 0.10 g/cm³, could indicate the formation of the planet outside the water snow line.

The research on hip 67522 B was carried out as part of the "Guest Observer" program of Cheops and the results were published in the renowned journal "Nature". There are also indications of the presence of another planet in the system, which opens up the possibility of observing further Stern Planet systems and examining similar phenomena.

relationships and future research

The knowledge of the exoplanet is not only fascinating, but also important for understanding the development of planetary systems in the universe. In this context, the Max-planck-Institut for astronomy Among other things about the genesis of stars and their planetary systems. The research here includes the analysis of physical and chemical processes that lead to the formation of planets and the development of new observation methods. It is expected that the discoveries on hip 67522 B also advance technical progress in astronomy.
