Hidden White Dwarfs Revealed | Science News

Astronomers have uncovered four hidden white dwarf stars nestled within binary systems just 65 light-years from Earth — including the ninth closest white dwarf to our Sun — using Hubble’s ultraviolet gaze to pierce through the glare of their red dwarf companions. These elusive stars, previously invisible in visible light, were revealed by filtering out stellar flares and detecting subtle radial wobbles caused by gravitational tugs. One system, G 203-47, took 27 years to confirm and features a red dwarf spinning unusually slowly, hinting at unique evolutionary paths. These findings not only expand our knowledge of nearby star populations but also suggest countless more hidden white dwarfs may lurk in unexamined red dwarf systems.
