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 "Atacama Large Millimeter/submillimeter Array (ALMA)" and “Submillimeter Array (SMA)” 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 earliest stage of star formation, and looking for a "first hydrostatic core", which is the object formed at the beginning of the star formation process.
