Bizzarro "super pianeta’ scoperto per la prima volta con osservazioni radio

Bizarre 'super planet' discovered for first time with radio observations

I ricercatori hanno scoperto un bizzarro “super-pianetafor the first time using radio observations, secondo un nuovo studio.

Known as BDR J1750+3809 or Elegast, il “super-pianeta” is actually a brown dwarf, a celestial object that is too cold and small to be a star. The discovery was made by researchers at the University of Hawaii, working in conjunction with tools from NASA and the Low-Frequency Array (PROMESSE) telescope in Europe.

This work opens a whole new method to finding the coldest objects floating in the sun’s vicinity, which would otherwise be too faint to discover with the methods used for the past 25 anni,” il coautore dello studio, Michael Liu, detto in a dichiarazione.

300 MILLION HABITABLE PLANETS EXIST, NASA SAYS

Brown dwarfs are generally harder to find using methods that astronomers normally use to find other stars. tuttavia, the light they emit at radio wavelengths was vital in the discovery of Elegast, the researchers added.

Since they lack the mass to trigger hydrogen fusion, they can’t be considered stars. Given their gaseous atmospheres, brown dwarfs resemble Jupiter and Saturn, the gas giants in our solar system, more than they resemble stars themselves.

We asked ourselves, ‘Why point our radio telescope at cataloged brown dwarfs?'” l'autore principale dello studio, Harish Vedantham, aggiunto. “Let’s just make a large image of the sky and discover these objects directly in the radio.

With the discovery of BDR J1750+3809, the researchers hope that more brown dwarfsthe closest things to exoplanetscould be discovered with radio telescopes.

The research has been published in the Astrophysical Journal Letters.

Più di 4,500 Finora sono stati scoperti esopianeti, con solo una piccola porzione pensato per avere le proprietà per contenere la vita.

In ottobre, un gruppo separato di ricercatori scoperto 24 potenziale “superhabitableplanets that may have conditions more suited to host life.
