Radiation Belt seen Outside Our Solar System for the First Time!

First Radiation Belt Discovered Outside Our Solar System

A team of astronomers has made a groundbreaking discovery by observing the radiation belt around a dwarf star outside our solar system. This is the first time such an event has been observed outside our own planetary system. The radiation belt was detected around a very cool dwarf star about 18 light-years from Earth. What makes this discovery particularly interesting is that the radiation belt around this dwarf star is similar in structure to the radiation belt around Jupiter. But it seemed about 10 million times brighter. In May 2023, astronomers using the Very Large Array (VLA) radio telescope in New Mexico observed a radiation belt around an ultracool dwarf star, the first ever seen outside the solar system. The star, named LSR J1835+3259, is about 20 light-years from Earth and has about 77 times the mass of Jupiter. The radiation belt is about 10 million times brighter than the radiation belts around Jupiter.

The discovery was made by a team of astronomers led by Melodie Kao, a postdoctoral researcher at the University of California, Santa Cruz. Kao and her colleagues were using the VLA to study LSR J1835+3259 when they noticed a bright radio signal coming from the star. The signal was coming from a region around the star that is thought to be where the radiation belt is located. The discovery of the radiation belt is significant because it provides new insights into the formation and evolution of exoplanets. Radiation belts can be harmful to life, so the presence of a radiation belt around an exoplanet could make it less likely that life could exist there. However, radiation belts can also be used to study the environment around an exoplanet. By studying the radiation belt, astronomers can learn more about the star’s magnetic field, its atmosphere, and its potential for habitability. The discovery of the radiation belt is a major step forward in our understanding of exoplanets. It is the first time that we have been able to directly observe a radiation belt outside the solar system. This discovery will help us better understand the potential for life on exoplanets and the environment around them.

 Here is some more information about the radiation belt that was observed around the ultracool dwarf star LSR J1835+3259.
The radiation belt is thought to be composed of high-energy electrons that are trapped by the star’s magnetic field. The electrons are thought to be accelerated by the star’s rotation, and they can reach energies of up to 100 MeV. The radiation belt is about 10 million times brighter than the radiation belts around Jupiter, and it extends out to about 10 times the radius of the star.
