Astronomers detect first known ‘death wish’ planet

View hidden hip 67522 is not great b. For the next 100 million years, strong magnetic fields and destructive cosmic radiation It will continue to eat on the remote planet and reduce it to a dimension similar to its current Jupiter -sized mass. Neptune. However, these apocalypse conditions are a nearby mistake. black hole. Instead, it is the result of astronomers that they define as a “adhesive” relationship with the host star of the outer planets.

“I have millions of questions because this is a completely new phenomenon, so the details are still not clear. He said in a statement.

For a long time theoreticalized but never observed, the first known “Planet with the desire of death” is explained in a study published on July 2, and is explained by his colleagues. Nature.

Astronomers using the European Space Agency Cheese The task caught a sticky outer planet that seemed to trigger radiation cartridges from the orbit star.

Astronomers have been studying this outer planet and host star Hip 67522 for years with NASA’s high -tech tools such as NASA’s James Webb Space Telescope and Transition Exoplanet Survey (TESS). They already knew that Hip 67522 was a little larger and cooler than our 4.5 billion -year -old sun, but at the same time only 17 million years old. Hip 67522 is also a much more active star than our sun and routinely emits much stronger energy cartridges. It also hosts both planets, but the hip has a orbit faster than 67522 B brother, and it takes only seven days to complete a circuit.

Ilin, “We have never seen any system like Hip 67522 before, when the planet was found, the host star was the youngest planet known to be in orbit in less than 10 days,” he said.

Knowing this, Iliin’s team decided to take a closer look at HIP 67522 B and joined the European Space Agency (ESA) exonet satellite Cheesefor help. Cheops can target and observe individual stars, and soon after the hip has documented intermittent cartridges from 67522.

“We have seen more flare with Cheops, we have increased the total count to 15, almost all of us come in front of the planetary star as seen from Earth,” he said.

This correlation implied that the interactions between the star and the planet are directly responsible for the cartridges. However, there was a problem with this probability: astronomers have long believed that the stars had only been independent of their host planets. So how can this be possible?

“15 flare in the hip 67522 set… [indicate] Permanent magnetic star in the system -Plan -Planet interaction, ”writers He wrote in his work.

Physics also supports the theory. Knowing the extremely close orbit of Hip 67522 B, this interaction may be possible if the star has a strong magnetic field. And considering the age of the hip 67522, this is almost a certainty.

Bombing with too much high energy radiation does not face well for the hip 67522 B. The planet is similar to Jupiter, but has the density of sugar rope, which makes it one of the most serial outer planets ever found. Over time, the radiation carried by the cartridges exceeds the thin atmosphere of the planet, that is, much faster than we think of the mass. In the next 100 million years, the hip 67522 B can go to the planet a much smaller Neptune than a Jupiter -sized planet. Credit: Janine Fohlmeister (Leibniz Astrophysics Institute Potsdam)

The current theory is that while gathering energy during the planetary orbit, some of them are directed to the waves along the magnetic field lines of the star, such as a whip breaking. When this wave reaches the end of the magnetic field line, it starts a large energy flare.

However, most of these powerful cosmic rays are not only thrown into the deep area, but instead, they are directed back to 67522 B with six layers of radiation, as they are in orbit at a safer distance.

“The planet seems to be triggering energetic cartridges,” he added. “The waves sent by the star along the magnetic field lines start the cartridges at certain moments. However, the energy of the fireworks is much higher than the energy of the waves.

This means that for the next 100 million years, all of this destructive energy will already wear a thin atmosphere and reduce the general mass of the planet. Finally, this atmospheric erosion hip 76522 b.

Fortunately, there is plenty of time for astronomers such as Iliin to continue to examine the unprecedented new finding. Researchers hope to follow their observations by identifying full energy types made by each glare. In the meantime, they plan to clean and find similar star plan systems to see if there is another desire to death there.
