I am 李亚光 (Li, Yaguang). 光 (guang) means light. Perhaps my journey with astronomy has been foretold by my name.
I currently work as a Beatrice Watson Parrent Fellow at University of Hawai'i. I obtained my PhD at the University of Sydney in 2023.
My research focus is asteroseismology, the study of oscillations in stars. When properly excited, a star we see in the night sky starts ringing, just like a musical instrument hitting some notes. I study these oscillations by measuring their brightness variations with space telescopes such as NASA’s Kepler and TESS missions. The goal is to understand why and how they oscillate.
As a beautiful tool, these oscillations can help us accurately measure how luminous, massive, and old a star is. I am also interested in using this information to date the history of the Milky Way and characterise exoplanetary systems.
