solar flare

n.
A sudden eruption of magnetic energy on or near the surface of the sun, usually associated with sunspots and accompanied by bursts of electromagnetic radiation and particles. Ultraviolet and x-ray radiation from solar flares often induce electromagnetic disturbances in the earth's atmosphere.

solar flare

n
(Astronomy) a brief powerful eruption of particles and intense electromagnetic radiation from the sun's surface, associated with sunspots and causing disturbances to radio communication on earth. Sometimes shortened to: flare See also solar wind

[ClickPress, Tue Feb 27 2018] Using data from the Atacama Large Millimeter/submillimeter Array (ALMA), a team of astronomers discovered that a powerful stellar flare erupted from Proxima Centauri last March.
Summary: TEHRAN (FNA)- A massive stellar flare on a baby star has been spotted by astronomers, shedding light on the origins of potentially habitable exoplanets.
A baby star's massive stellar flare was recently spotted by astronomers, who speculated that it may shed light on the secrets of the origins of potentially habitable exoplanets.
The term is also used to refer to similar phenomena in other stars, where the term stellar flare applies.
On April 25th it shot off the brightest stellar flare ever seen, and for a few minutes EV Lac became a naked-eye star.
Thanks to the flare's strength, Osten's team identified direct evidence of charged particles being accelerated along the star's magnetic-field lines--an early stage of a stellar flare. While a full-blown flare releases a burst of radiation across a wide swath of the spectrum, the particle-acceleration signatures are fainter and isolated to just a few spectral regions, including high-energy X-rays.
"This is the largest stellar flare ever recorded in ultraviolet light," says Welsh.
However, Arney suggested that K stars are more likely to host habitable worlds over M stars because the latter experiences more extreme activity during their youth, releasing powerful stellar flares more often than young Sun-like stars.
