I am 李亚光 (Li, Yaguang). I am an astronomer, now working as a Beatrice Watson Parrent Fellow at University of Hawaiʻi at Mānoa. I obtained my PhD at the University of Sydney in 2023.

I am broadly interested in stellar astrophysics and specialize in asteroseismology, the study of stellar oscillations. Almost every star on the sky pulsate, just like a musical instrument hitting some notes. I study these variabilities to understand the physics of stellar interiors, through precision stellar modeling and diagnostic observations, using data from space telescopes (Kepler, TESS, PLATO, Roman) and ground-based facilities (SONG, Keck/KPF, and VLT/ESPRESSO). 

Stars are also wonderful tracers. I work on stellar characterization to study Galactic archaeology, star-planet interaction, and exoplanet characterization.
