Astronomers discover two new giant planets

A group of scientists including two astronomers from the University of Chile, they found two planets the size of Jupiterwho have been identified as K2-237b and K2-238b. According to the doctor in Astronomy of the University of Chile, and currently a postdoctoral researcher at the University of London Queen Mary, Maritza Soto, the two planets they are composed of hydrogen and helium.

However, they found an interesting detail in the K2-237b, and it is that this planet has a larger size than what the theory indicates. Possibly this size is the cause of the amount of radiation that it receives.

"The main contribution of the research is that it provides evidence for the study of the inflation of planets, a phenomenon seen on many planets (called) & # 39; Hot Jupiter & # 39 ;, but we still can not understand that at all, "the doctor emphasized Soto.

How did you manage to discover them?

The scientists used various elements that led to the discovery of these two planets, most of which occurred in the Observatory The President of the European Southern Observatory (ESO), in the northern desert of Atacama, the most important intergovernmental astronomical organization Europe and the most productive astronomical observatory in the world.

Among those elements were a Swiss 1.2-meter telescope, a 2.2-meter telescope and a 3.6-meter telescope.

The communiqué of this discovery was disseminated by the Center of Excellence in Astrophysics and Related Technologies (CATA).

The two planets of circular stars are similar Sol and they are nearly 1,500 light years away from the Earth, in constellations of Ophiuchus and Aquarius.

undergrowth He explained that the next step in this line of research, involving a dozen or so scientists, will be to study the atmosphere of the planet. K2-237b.

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

The planet K2-237b to spin his star every two days, while the second, K2-238b, carries out his job for three days.

What are the hot Jupiters & # 39;

They are planets with at least a third of the surface of & # 39; Hot Jupiter & # 39;in addition to a job near his star and therefore the temperatures are very high.

The orbital periods of the & # 39; Hot Jupiter & # 39; they are less than ten Earth days while the orbit of our Jupiter – the year – is equal to twelve years of our own and the distance to the sun makes it much colder than the earth.

The finding is the result of the work of several years of a team of scientists from Chile, Brazil and Europe, led by Roberto Saglia, from the Max Planck Institute for Extraterrestrial Physics, in Garching, Luca Pasquini from ESO.
