Named in honor of Philippe Lamy, since 1973 a staff scientist at the Laboratoire d’Astronomie Spatiale, Marseilles. Lamy has been involved in studies of solar-system dust for more than 20 years. He has specialized in circumsolar, interplanetary and cometary dust, particularly in their optical and light-scattering properties. He is currently studying cometary nuclei using HST and ISO and is involved in a number of space missions (SOHO, Cassini and Rosetta). (M 27458) _ _.
