The synthetic ALMA multiband analysis
The synthetic ALMA multiband analysis
The dust properties in the protoplanetary disks is very essential information to understand the planet formation processes and disk evolution. The multiwavelength analysis is one of the powerful tools to derive the physical properties from the observational data. I test the synthetic ALMA multiband analysis to find the best three ALMA band combination for constraining the dust temperature, optical depth, and dust opacity power-law index š¯˛« from the ALMA archival data of the TW Hya disk.
The dust gap-ring
The dust gap-ring
I detect the dust gap-ring structure in the CR Cha disk at the first time. Also, the CO emission lines provide the gas properties in the disk. Based on the observed dust and gas properties, I suggest two possible origins of the gap-ring structure.
