1. Circumstellar Debris Disks : Observational Studies of Cold Dust and Gas Emission in Planetary Nurseries
Abstract : Planetary systems form in disks of gas and dust surrounding newborn stars. The young circumstellar environment is characterized by frequent collisions between rocky bodies, leading to a continuous production of small dust grains. READ MORE
