I am 李亚光 (Li, Yaguang). 光 (guang) means light. My journey with astronomy has been foretold by my name.
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 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 with space telescopes such as NASA’s Kepler and TESS missions and ground-based RV facilities such as SONG, Keck/KPF, and VLT/ESPRESSO.
As a remarkable tool, these oscillations help us accurately measure how luminous, massive, and old a star is. I am interested in applying this information to age-date the evolution of the Milky Way and characterise exoplanets. I am also interested in advancing our analytical methods to understand the physics of stellar interiors.
