Why some planets eat their own atmosphere?

Surface exoplanets an artist's concept of
For many years our Solar system was the only one in the Universe. At least I thought so mankind before the discovery of the first exoplanet in the late 1980-ies. That is since the best telescopes in the world gradually began to open a whole treasure trove of planets orbiting distant stars, to the end of 2019, with as many as 4133 instance. When in 2014, the space telescope gave scientists a list of more than 700 new distant planets — many of them were similar to what we saw earlier. In contrast to the gas giants, such as which is easiest to detect from earth orbit, the new planet was smaller and mainly had a rocky surface. The properties of these highly unusual objects could truly astound astronomers.
What are the strangest exoplanets in the Universe?
In the Universe you can find a great number of exoplanets, whose dimensions are either very similar to earth, or very different from them. However, the scientists were able to detect unusual strangeness, which is manifested in the fact that when the exoplanet three times the size of Earth, it suddenly ceases to grow.
According to the information portal , scientists from Washington University were able to find an original solution to this cosmic puzzle. According to their official statement, the oceans of magma on the surface of some planets easily absorb their atmosphere upon reaching the stony object is particularly large.
Perhaps it is the telescope, TESS will be able to shed light on the actual look of the planet-subnature
Covering a large part of the molten magma oceans do not freeze over time, gradually filled with its own hydrogen atmosphere and eating away at the “sky”. In this scenario, the pressure in the place where the atmosphere meets the magma begins to grow. First magma absorb added gas with constant velocity, but with increasing pressure, the hydrogen begins much easier to dissolve in the magma, at the same time slowing the growth of the planet, seeking to reach the size of Neptune.
Despite the fact that in Solar system there are planets that could boast such a unique ability to absorb an ocean of magma gas shell of the planetary object, future research telescope TESS could shed light on the theory of scientists from Washington. In addition, a number of already discovered exoplanets, whose dimensions exceed several earth, may fall into the category of such planets, which significantly reduced our chances of detection .
