‘Goldilocks’ stars may pose challenges for any nearby habitable planets
If you’re an aspiring life-form, you might want to steer clear of planets around orange dwarf stars. Some astronomers have called these orange suns “Goldilocks stars” (SN: 11/18/09). They are dimmer and age more slowly than yellow sunlike stars, thus offering an orbiting planet a more stable climate. But they are brighter and age faster than red dwarfs, which often spew large flares.
