Ganesar Chanmugam (1939-1996) was a superb teacher and cherished colleague of the physics and astronomy faculty at Louisiana State University. Born in Colombo, through more than 25 years of research he made broad contributions to our understanding of the magnetic and radiative properties of neutron stars and white dwarfs.Naming citation (20010509/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
