The Hakubi Project

Short Introduction

I specialize in stellar astronomy, focusing on the study of stellar energetic explosions, called “superflares”. The superflares are quite rare on our present-day Sun while they are frequent on young stars and possibly on the ancient Sun. The high-energy radiation and particles from the superflares can severely influence the evolution of the atmospheres of surrounding young planets. My goal is to investigate the nature of these explosions to determine the potential habitability of these planets.

In the Hakubi Project, I will focus on young Sun-like stars that is like our Sun in its youth. By using telescopes and satellites worldwide, I will observe these unpredictable superflares across multiple wavelengths and investigate the disturbances they cause in the stars' astrospheres. By observing young Sun-like stars at various ages, I hope to reveal the characteristics of astrospheric disturbances and their evolution with age, providing insights into the evolution of our own Sun in its youth. This research is directed at elucidating the relationship between the Sun and Earth during the critical epochs for the origin of life.
