The discovery of an exoplanet the size of Neptune with an atmosphere that may contain water vapor


Astronomers have identified a new exoplanet the size of Neptune with a “large atmosphere”, and its clouds may contain water vapor, according to a new study, and the exoplanet is known as TOI-1231 bIts orbit extends over 24 days around its star. TOI-1231, and can have an atmosphere similar to Neptune, due to its size and density.

According to the website,RTThere is also the possibility of water vapor on the planet, which is 90 light-years away from Earth, which interests scientists.

“The low density of TOI-1231 b To that it is surrounded by a large atmosphere and not a rocky planet. But the composition and extent of this atmosphere is unknown.”

Dragomir continued, “It can contain TOI-1231 b On a large atmosphere of hydrogen or hydrogen and helium, or the atmosphere of more dense water vapor. Each of these elements points to a different origin, allowing astronomers to understand whether and how planets form differently around red dwarfs when compared to planets around our sun.“.

It is known as red dwarfs, or cold dwarfs (Little stars of a kind M), They are types of stars much smaller than the Sun, and their masses range between 8% and 50% of the mass of the Sun. It is the most abundant class of stars.

Water vapor may be on TOI-1231 b Just a possibility, but it’s still one of the coolest exoplanets ever discovered, with a predicted temperature of 140 degrees Fahrenheit.

Previous studies have suggested that planets with such a temperature can have high atmospheric clouds, but more research on exoplanets K2-18 b Shows the possibility of water in the atmosphere.

The exoplanet was discovered by a transiting exoplanet survey (TESS) of NASA and later confirmed using a spectrometer Planet Finder Aboard the Magellan Clay Telescope at Las Campanas Observatory in Chile.

The study’s lead author, Jennifer Burt, said the researchers were able to measure the radius and mass of the planet, which allowed them to theorize that it is similar in composition to Neptune..

“These values, in turn, allowed us to calculate the bulk density of the planet and hypothesize what it is made of,” Burt explained“.

Scientists hope to further examine the planet’s atmosphere using the Hubble Space Telescope and the James Webb Telescope, due to launch later this year..

“This new planet we’ve discovered is still strange, but it’s a step closer to being somewhat like our neighboring planets,” Burt said. “Compared to most transiting planets discovered so far, which often have extreme temperatures of several hundred or so. Thousands of degrees, the TOI-1231 b Positively frozen.”
