Jupiter-sized star produced a white-light superflar and astronomers noticed it



Recently, a small star similar in size to Jupiter has found a so-called Jupiter star, 250 light-years from Earth, causing a huge flare. At that moment, the star released the energy equivalent of 80 billion tons of TNT. At the same time, the brightness was 10,000 times greater than usual.

In addition, it was ten times stronger than any outbreak from the Sun so far. This includes the significant Carrington event, which took place in 1859 and affected the telegraph services around the world. In addition, it had triggered different auroras.

A Jupiter star still has a strong magnetic field that allows white light superflares

James Jackman is a Ph.D. student at the University of Warwick. He is also the lead author of an article dealing with the breakout issue. According to him, you will notice that the activity of the stars decreases the more you go to lower and lower masses. Scientists continue to expect the source of the flare (the chromosphere) to weaken or cool.

Jackman adds that this shows that there is still strong magnetic activity at this level, as evidenced by the white light flare. The star that was noticed is actually an L-dwarf. The official name is ULAS J224940.13-011236.9. For those of you who may not know it, L-Dwarfs are one of the lowest mass bodies you can call a star. They are actually a middle ground between stars and brown dwarfs.

Finally, the scientists hope to find out more about the bright light reflections and their formation after the flare in August 2017. The most exciting thing about them is that they contain high-energy UV emissions that can help initiate biological activities. This could even be an essential starting point for further exploration of cosmic activity and its relationship to our life on earth.
