Chilean astronomers discover two new giant planets



Chilean scientists discovered two new exoplanets of the "hot Jupiter" type, huge gas balls similar to the solar system galaxy, according to a statement issued today by the Center for Excellence at Astrophysics and Allied Technologies (CATA).

Both objects identified as K2-237 b and K2-238 b, orbit around stars similar to the sun and nearly 1500 light years of the earth, in the constellations of Ophiuchus and Aquarius, indicate Report21.

The first of the planets (K2-237 b) rotates around its star every two days, while the second (K2-238) runs for three days.

Both objects have a mass that is slightly higher than Jupiter, the fifth planet of the solar system and this is part of the so-called outer or gaseous planets.

"It is estimated that both planets consist mainly of hydrogen and helium," said the physician in Astronomy at the University of Chile, and currently a postdoctoral researcher at the University of London, Queen Mary, Maritza Soto.

Soto, who led the research, explained that there is an important detail in this discovery: the K2-237 b is an inflated planet, that is, the size is much larger than what the theoretical models indicate, because it is a very interesting planet for studies is atmospheric.

According to scientists, the theory states that inflation is caused by the heat that falls on the planet of the star, which penetrates deeply and blows it up like a balloon.

"The main contribution of the research is that it provides evidence for the study of inflation of planets, which is a phenomenon seen on many planets (called" hot Jupiter "), but we still can do not fully understand, "he emphasized Dr. Soto.

He explained that the next step in this line of research, in which a dozen scientists have participated, is to study the atmosphere of the planet K2-237 b.

"That will not be immediate, but we hope that data for that purpose will soon be collected," concluded the astronomer.

To detect these planets, various instruments were used in Chile, most of which are located in the La Silla Observatory of the European Southern Observatory (ESO), in the northern Atacama desert, the main intergovernmental astronomical organization in Europe and the astronomical observatory. . productive world.
