In fact, the amount of UV radiation emitted by this class of stars could render any orbiting planets uninhabitable, despite being in the ⁘goldilocks⁘ zone .
Unmasking this cosmic conundrum, researchers from the University of Hawaiʻi Institute for Astronomy ( IfA ) step into the spotlight.
The study was led by astronomers Vera Berger and Benjamin J. Shappee and their fellow researchers at IfA. They've pulled back the cosmic curtain to give us a fresh view of these celestial firecrackers, presenting an intriguing, more nuanced narrative.
The researchers discovered that red dwarf stars can produce stellar flares emitting far-ultraviolet (far-UV) radiation at levels much higher than previously presumed.
The million-dollar question is: How does this intense UV radiation from these flares impact the habitability of planets around the red dwarfs?
⁘Few stars have been thought to generate enough UV radiation through flares to impact planet habitability. Our findings show that many more stars may have this capability,⁘ Berger divulges.
