Researchers from the University of Oviedo discovered and characterized a planet located in the habitable zone of a red dwarf star. ) discovered and characterized a super-Earth orbiting the habitable area of a red dwarf M0 type called K2-286. For this, they used data from the Kepler Space Telescope
. The Kepler satellite was designed to discover exoplanets. The research method consists of measuring the brightness of a star and observing if its luminosity decreases periodically, as in an eclipse. If this change in brightness occurs, a planet regularly pbades in front of the star.
The star K2-286 located in the constellation Libra at a distance of 244 light-years, has a radius of 0.62 sunrays and an effective temperature of 3650 ° C The planet has 2.1 times the radius of the Earth an orbital period of 27.36 days and a temperature of equilibrium of up to about 60 ° C.
The planet, according to the 39; study published in is located on the inner boundary of the habitable zone so that, under good conditions, it can retain liquid water on its surface, an indispensable condition for the development of life as we know it.
The planet is of particular interest not only to be located in the habitable zone of its star, but to be one of the most suitable for future atmospheric characterization of the James Webb Space Telescope as well as for surveillance to establish its mbad with precision.
"We found that the activity of the stars is moderate compared to other stars without characteristics."
"This exoplanet could be a good candidate for a new generation instrument such as that ESPRESSO, recently installed in the VLT telescopes of the Observatory.Parbad (Chile), "adds Jonay González, researcher at IAC
