After thirty years of investigation, a team of scientists from six European countries reports that the hypergiant star HR 8752 is partially traversing the Yellow Evolutionary Void,
an area in the Hertzsprung-Russell diagram empty of hypergiant stars with surface temperatures between 5000 and 12000 degrees kelvin. Some of the observations were carried out
using the Utrecht Echelle Spectrograph (UES, now retired) on the William Herschel Telescope.
