‘Marshmallow’ world defies expectations for planets at pink dwarfs


Astronomers have found a fuel big planet with the density of a marshmallow orbiting a cool pink dwarf star positioned 580 light-years from Earth. The Jupiter-like exoplanet is the lowest-density world ever noticed orbiting a pink dwarf.

Crimson dwarf stars are the smallest and dimmest stars that are nonetheless changing hydrogen to helium of their cores by means of nuclear fusion, a stage of a star’s life that astronomers referred to as the “essential sequence.” Though a lot cooler than the solar, pink dwarfs are identified to be extraordinarily energetic and launch highly effective flares that may strip the atmospheres of any orbiting planet.
