For the first time outside the solar system discovered aurora


Astrophysicists from the University of Leicester was the first to detect extra-solar aurora. Summary of the scientific articles published in the journal The Astrophysical Journal, can be found at TGDaily.

Charged particles from interstellar space collide with atoms of the atmosphere of a celestial body - so the formation of polar auroras. This phenomenon can be seen not only on Earth, auroras recently, for example, it was discovered by scientists in the atmosphere of Venus. These lights are also observed on Mars, where they occur, despite its name, and on the equator. This is due to the fact that the field of the planet is an existing balance once the full field.

The research has included the use of specialist model of nucleation currents in the atmosphere as a result of lights, on the example of the gas giants - Jupiter. Researchers have extended it to the case of brown dwarfs - celestial bodies that are intermediate between the gas giants and stars. The mass of these bodies, on the one hand is enough to make them in a certain stage of their development occurred thermonuclear reactions, on the other hand, this mass is not enough to sustain the process of supplying the energy of ordinary stars - "burning" of hydrogen.

The model allowed the scientists to understand the characteristics of electromagnetic radiation dwarfs. Around the failed stars, as a consequence of the model the researchers, there is a strong need to shine. This kind of electromagnetic tracking for terrestrial aurora was recently recorded, and even turned into sounds. As they note, these are the first results of this kind for objects outside the solar system.
