The hottest exoplanet in the universe

The hottest exoplanet in the universe

Extreme exoplanets are a good source for making interesting theories about the other exoplanets and their role in the planetary systems and even the bearer of lifeforms, which might be very primitive. The hottest known exoplanet KELT9b has a strange meteorological phenomenon, where the rising gas pylon causes the situation, that the atmosphere is heating in ultra-hot temperature. The temperature of an atmosphere of that planet is hotter than the star, what it orbits. 

This strange world might not have any lifeforms, because it's like some hot Jupiter. In some scenarios, this kind of planet would have the gas-geyser in the atmosphere, and that kind of thing allows that the gas from the atmosphere would not flee to the universe or central star of that system. 

In this kind of scenario, the gas would rise to upwards and when gas layers and dust are touching together the temperature of that planet's atmosphere would raise extremely hot because of friction, which would turn the planet extremely hot. If the distance of the planet to the central star is high enough the gas would drop back to the atmosphere.  

But if the planet is too close, that gas would be sucked to the star. If the planet would consist of the heavy elements, that distance can be quite small, and if the entire planet would be made by Crypton, that would be a very heavy object, because element or noble gas Crypton is the heaviest stable element on nature. And if that element forms the Jupiter-size object, that would have an extremely high power gravity field, because that element is so heavy, but the question is "could the noble gas form the planet?". 

That thing has caused the thoughts that are it possible that some planet a similar phenomenon would make the planet, which is a very long distance away from the central star's ability to have liquid water. The theory of this phenomenon has caused because there is a possibility that the friction between the gas layers in the planet atmosphere would make it possible that the temperature on the surface of that planet would allow the existence of liquid water. 

That doesn't mean that there could be any kind of animal or other life forms, except the primitive bacteria, which would live in the water. Those hypothetical organisms get their energy from volcanic heat. In this case, the upper atmosphere of this hypothetical planet would shine in the extremely high temperature, and the friction would shine heat to the surface of that planet. 

The reason why the higher life forms would not probably live on that yet fictional planet would be that the distance between that planet and the central star could be so big, that the radiation of that star would be extremely low, and that's why photosynthesis would not be possible. In some other theories or scenarios, the fast-rotating atmosphere of the planet would melt its entire lithosphere. 

If the planet would have that thing, and then the heated atmosphere would work as the sun for some moons, which is orbiting that planet. The idea is that in this kind of cases the moons of this kind of extreme hot planet would be habitable if their atmosphere would be stable.
