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

Researchers have discovered a bizarresuper-planetfor the first time using radio observations, volgens 'n nuwe studie.

Known as BDR J1750+3809 or Elegast, die “super-planetis 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 (LOFAR) 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 jare,” the study’s co-author, Michael Liu, gesê in 'n verklaring.

Brown dwarfs are generally harder to find using methods that astronomers normally use to find other stars. Egter, 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?'” die hoofskrywer van die studie, Harish Vedantham, bygevoeg. “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.

Meer as 4,500 exoplanets have been discovered so far, with only a small portion thought to have the properties to contain life.

In Oktober, a separate group of researchers ontdek 24 potensiaal “superhabitableplanets that may have conditions more suited to host life.
