Despite the intense influence of the red star, they discovered a rare planet with an atmosphere

And extraterrestrial Rare, nicknamed the ‘Phoenix’ for its ability to retain the radiative energy of its red giant star, explains the vast diversity of solar systems and the complexity of planetary evolution, particularly at the end of stars’ lives.

Scientists have discovered something new the planet beyond the solar system, ‘Phoenix’ It protects its atmosphere regardless of the intense radiation it receives from a Estrella Nearby, a discovery that calls into question current theories about how animals age and die. Planets In an extreme environment.

A The study was published Wednesday in The Astronomical Journal Researchers believe this extraterrestrial “Thin must have been reduced to mere rock by intense radiation Estrella Smaller, older and hotter than they thought”.

A nickname ‘Phoenix’ By researchers, for its ability to withstand radioactive energy Estrella Giant Red, The extraterrestrial It has created an unusual fluffy atmosphere.

“This the planet It doesn’t evolve as we thought because it shows a much larger and less dense atmosphere than we believed would be subjected to more extreme conditions,” says Sam Gruenblatt, an astrophysicist at Johns Hopkins University in the US, one of the authors of a report from the center.

A ‘Hot Neptune’

New the planet It belongs to a class of rare worlds known as ‘hot Neptunes’ because they share many similarities with giants. the planet Ice cream outside the solar system, though very close to it Stars Hostesses and be very warm.

‘Phoenix’ It is 6.2 times larger than Earth, completing its orbit Estrella Mother every 4.2 days and 6 times closer Estrella than Mercury from the Sun.

Scientists evaluate this extraterrestrial It is 60 times less dense than the largest ‘hot Neptune’ discovered to date, and will not survive for more than 100 million years before it begins to die, drifting towards its surface. Estrella Colossal.

“about that the planet One of these is the smallest we’ve found around Stars Red giants, and probably very little mass around Estrella The host we saw, that’s why she looks so weird,” says Gruenblatt.

“We don’t know why it still has an atmosphere when other much smaller and denser ‘hotter Neptunes’ lose them in much less extreme environments,” he adds.

The end of the stars’ lives

Los Extraterrestrials as ‘Phoenix’ They are not often discovered because their small size makes them more difficult to spot compared to larger and denser ones; The discovery was made possible by a new method for correcting satellite observation data at this level Extraterrestrials From NASA.

According to the authors, ‘Phoenix’ Explains the enormous diversity of solar systems and the complexity of planetary evolution, especially at the end of planetary life. Stars.

“We don’t understand the late evolution of planetary systems very well. This tells us that Earth’s atmosphere may not have evolved as well as we thought,” says Gruenblatt.

For now, scientists predict that the Sun will expand in a few billion years Estrella A red giant that swells up and engulfs Earth and the rest Planets Indoors, but findings like this may call this theory into question.
