Effects of scattering and dust grain size on the temperature structure of protoplanetary discs: A three-layer approach

, 2008
The temperature in the optically thick interior of protoplanetary discs is essential for the interpretation of millimeter observations of the discs, for the vertical structure of the discs, for models of the disc evolution and the planet formation, and ...
