Research Interests

"How stars like our sun are formed?" -- this is one of the most fundamental problems in astronomy. Since stars are formed deeply inside of the interstellar molecular clouds, we need to look into the dusty cocoons that are obscuring the light from newly-born stars. Radio eyes such as “Submillimeter Array” on top of Mauna Kea help us to study what is going on inside of the cocoons. Using the radio eyes, I am studying the structure and physical condition in the close vicinity of the newly-born stars. I am especially interested in the energetic outflow phenomena that are frequently associated with the potostars in the earliest evolutionally stage.
