Task Description and Goals

Circumstellar disks are sites of planet formation but their characteristics are poorly understood especially in protostellar systems, where disks are deeply embedded in the infalling envelope. In this project, we aim to determine properties of the disk around protostars such as temperature, strength of turbulence and so on using observatioal data of Atacama Large Millimeter/submillimeter Array (ALMA). We will analyze molecular line data, and investigate gas kinematics, line intensity ratio and so on.

Students are expected to learn how to analyze ALMA data and interpret the observational data mainly from the point of view of the gas kinematics through this project.

Required Background

Knowledge of basic physics and english communication skill. It would be better if the applicants also have experience in UNIX/LINUX systems and programing languages such as Python.
