The high-resolution images obtained with a large array of radio dishes revealed 'persistent, intense radio emissions' from this stellar object.
Astronomers have discovered evidence of a radiation belt outside our solar system for the first time.
"We are actually imaging the magnetosphere of our target by observing the radio-emitting plasma—its radiation belt—in the magnetosphere. That has never been done before for something the size of a gas giant planet outside of our solar system," said Melodie Kao, a postdoctoral fellow at the University of California in Santa Cruz and first author of this study, in anA magnetosphere is the magnetic field-dominated region surrounding a celestial object, where charged particles are trapped.
For example, the Earth's interior is hot enough to have electrically conducting fluids, which aids the generation of its strongIn the case of Jupiter, the liquid metallic hydrogen generates a magnetic field. According to Kao, metallic hydrogen in the interiors of brown dwarfs could possibly result in the generation of magnetic fields.
