Meredith McGregor of the University of Colorado at Boulder and her colleagues are recent In their studies A record-breaking tendency was reported for Proxima Centauri at 4.24 light years, according to the reports ScienceAlert. The flyers form some kind of stellar activity and represent a sudden brightening of a portion of the atmosphere.
Proxima Centauri is a red dwarf, such things are relatively cool, but this does not mean that they are not active. Excessive activity is not good news for local planets in terms of life: the star’s radiation will likely make it impossible for complex organic molecules to remain on the surface of celestial bodies long enough for life forms to appear.
In 2019, McGregor observed Proxima Centauri for 40 hours with a system of nine binoculars and a space telescope. Devices used included ALMA (Atacama Large Millimeter / submillimeter) and TESS (Transient Exoplanet Survey Satellite). “This is the first time that we have studied a stellar fleet in such a comprehensive coverage of the wavelength,” said MacGregor.
Five members of the network were able to observe the event. This was a highly developed phenomenon, as the radiation was documented 14,000 times in some ranges of electromagnetic radiation. According to the researchers, this was the largest activity ever observed. The team also observed intense brightness in the millimeter range, and a similar observation had not been made before.
Experts are confident that similar studies at many wavelengths will give them a better understanding of the behavior of stars.
