ABSTRACT

Transition disks represent an intermediate stage between primordial disks and debris disks. Both theories and observations believe that planet formation is most probably ongoing in these evolved protoplanetary disks. Therefore, detailed investigation of the transition disk structure plays a key role in understanding the evolution of protoplanetary disks and the processes of planet formation. In this project, we will select a large sample of transition disks from the Chamaeleon II, Lupus, Perseus, Ophiuchus and Serpens star formation regions with same criteria, and conduct thorough modeling work of their observed spectral energy distributions (SEDs) under an identical assumption of the radiative transfer model. Based on the results of SED analysis, we will systematically study the properties of transition disks like the scale height, flaring index and the disk mass in a statistical way, and try to establish the relationship between the properties of the transition disks and those of the central stars. Meanwhile, we will classify the whole sample into the class of canonical transition disks and that of the homologously depleted disks, and try to find differences in the structure between these two disk categories. We will also study how the environments influence the disk evolution by comparing the structure of transition disks in the five different star formation regions examined in our project. Moreover, we will propose high resolution observations for some promising homologously depleted disks in our sample. These newly obtained data will help us to find evidences of initial processes of planet formation, such as dust growth and settling that probably present in this kind of transition disks. More... »
