  • sorae – A flare 100 times stronger than a solar flare occurred at Proxima Centauri

This is the “An artistic rendering of the powerful flare that occurred at Proxima Centauri“He is.

A research group announced in 2021 that multiple flares, including one about 100 times more powerful than solar flares, had been detected in Proxima Centauri, the closest star to the Sun. Two exoplanets have been reported so far in Proxima Centauri.(※)However, according to the research group, these planets may experience flares on a daily basis.

*Following this announcement, there was a report that a third planet candidate, Proxima Centauri C, had been discovered, but due to the lack of clarity, the information at the time was listed as “two”.

In order to better understand the red dwarf's flares, the research group observed Proxima Centauri for a total of 40 hours in 2019 using nine telescopes on Earth and in space, including the Hubble Space Telescope and ALMA. As a result, an outbreak occurred on Proxima Centauri.Detect multiple flaresIt is said that he did.

Of particular note is a 7-second flare that was detected by five telescopes on May 1, 2019. According to the research group, although this flare did not emit much visible light, it was very bright in the ultraviolet and millimeter waves (waves Radio with a wavelength of 1 to 10 mm), which increased the intensity of ultraviolet light by about 14,000 times, is said to have been achieved.

Park Lloyd of Arizona State University, who participated in the research, recalls that when he saw observational data from the Hubble Space Telescope that captured the ultraviolet light emanating from the flare, “I knew immediately that we had captured an amazing phenomenon.” Maso. As we mentioned at the beginning, this flare is about 100 times more powerful than similar flares that occur on the Sun, and is said to be the largest flare ever discovered on Proxima Centauri.

According to McGregor,Planets orbiting Proxima Centauri may experience at least one flare per dayThere seems to be.
