Meet the members of our lab.
We study various stars and planets orbiting around them (exoplanets) through astronomical observations using large telescopes.
Our research targets are familiar and well-known stars, various types of stars that exist widely from the solar neighborhood to the galaxy, and unknown planets orbiting them.
The joy we feel when we come across a new discovery through observation is irreplaceable, but unfortunately, there are also times when we find nothing. However, research is about doing something meaningful even when nothing is found. Let's explore the world of exoplanets with ideas and perseverance.
