A group of researchers in which the ULL collaborates detects a new anomalously thin little exoplanet

Every week, telescopes around the world detect new exoplanets,
that is, celestial bodies orbiting around different stars
to the Sun, but the last one found by the United Kingdom InfraRed
Telescope (UKIRT) in Hawaii, goes out of the ordinary: "The importance of
this discovery is that the planet is very swollen, what
which challenges the conventional models of planetary evolution and supports
the hypothesis that this type of planets may have been formed from a
way radically different from those of the Solar System ", comments Eduardo
Martín, researcher at the Center for Astrobiology at CESIC (CAB).


This finding, in which the ULL has also collaborated, has been
recently published in the Monthly Notices of the Royal magazine
Astronomical Society, under the coordination of the CAB researcher & nbsp;
David Barrado, for whom this work is "a clear example of the
international coordination and the need to investigate different
exoplanetary environments ".


These theories predict that the radii of the newly formed planets
they decrease with the passage of time as they radiate their energy
internal However, considering that the exoplanet discovered,
that has been christened WTS-1b, and its progenitor star was formed
600 million years ago, the body should have a size of 20%
higher than Jupiter and not 50%, as observed. One possible
explanation is the great closeness between WTS-1b and its star, which makes
that the exoplanet has not cooled down so quickly and kept
"Inflated".
