1862‐1934 Swedish astronomer. Professor of astronomy at Lund University from 1897 to 1927. In 1908, he proposed the hierarchical cosmology as a solution to the HWM Olbers paradox. Although the paradox has now been resolved in the relativistic universe, Charlier's hierarchical universe is embodied in a series of galaxies, galaxy clusters, superclusters, and so on. From his research into the spatial distribution of B-type stars in 1916-22, he discovered a stellar group containing the sun, with a diameter of 2,000 light years and a thickness of 700 light years, known as the Local System.
