| Abstract |
Recent theoretical studies have revealed that porosity evolution of aggregates plays a crucial role in dust evolution in protoplanetary disks. In this talk, I will present how the porosity evolution affects the observational appearance of the disks at millimeter wavelengths. Based on the results of our global dust growth simulations that take into account porosity evolution, we show that the porosity evolution leads to an abrupt decrease in the mm optical depth in an inner disk region. We also find that the high-porosity aggregate model predicts the absence of the peak in the radial distribution of the mm opacity index \beta. These features will allow to test porosity models with ALMA observations. |
