A group of astronomers from the University of Chile has carried out an investigation in which they have discovered a new exoplanet with an orbital period of 19 hours, 1,700 degrees Celsius temperature, with its own atmosphere and at a distance from La Tierra de 260 light years.
The exoplanet, named LTT 9779 b, has been located in the Neptunian Desert and its discovery could influence future studies on Neptune’s atmosphere that could unravel mysteries related to the formation of other exoplanets or explanations about their evolution.
According to the professor in charge of the study, James Jenkins, corresponds to the first “Ultra hot Neptune “ discovered, a finding “unlikely, because it is in a region called ‘the Neptune Desert’, where there are almost no planets.”
“This region is characteristic because their planets have orbital periods of less than four days, and with similar masses and sizes Neptune “, explained James Jenkins, adding that” this allows the investigation of its atmosphere (…) In the case of the planet LTT 9779 b, it still has an atmosphere despite its proximity to the star that orbit. It is very difficult to explain why this planet did not become a rock core. I don’t think we can find many more examples like this orbiting other such bright stars. “
According to the University of Chile in a statement, the system to which LTT 9779 b belongs “is about half the age of our Sun, that is, about 2 billion years. The intense radiation from the star does not it should allow an atmosphere similar to Neptune to exist, to remain for so long. “
For Jenkins, this discovery is relevant for future research, as “It will allow us to understand much more about the chemistry and physical processes of the atmospheres of planets with characteristics similar to Neptune; the exo-Neptunes. This will allow us to learn much more about the processes of formation and evolution of planets in general, it is a very special planet ”.
