Why Is Sun Kwok Influential?

(Suggest an Edit or Addition)

According to Wikipedia, Sun Kwok is a Hong Kong astronomer best known for his work on physics and chemistry of the late stages of stellar evolution. In 1978, he proposed a new theory on the origin of planetary nebulae. which has transformed our understanding of the death of Sun-like stars. He is a pioneer on the study of stellar synthesis of organic compounds, which may have implications on the origin of life on Earth.
