Zhanwen Han

Character introduction

Experience of education and training
Prof. Dr. Zhanwen HAN obtained his BSc degree from Hebei University in 1984, an MSc degree from Yunnan Observatory in 1987, a Ph.D. degree from the University of Cambridge in 1995, and did a postdoc at the University of Science and Technology of China from 1996 to 1998.
Positions
an Academician, a chair professor at the Yunnan Observatories of the Chinese Academy of Sciences.
Research and achievements
Zhanwen Han’s research interest focuses on stellar evolution, binary evolution, binary population synthesis, the formation of various binary related objects (e.g., type Ia supernovae, hot subdwarfs, double compact objects), evolutionary population synthesis, far-UV radiation of early-type galaxies. He joined the International Astronomical Union (IAU) in 1996 and was elected as the chair of the IAU Finance Committee (2015-2018) and a member of the IAU Stellar Evolution Organizing Committee (2015-). He was elected as a fellow of the Royal Astronomical Society (2000-) and a vice-president of the Chinese Astronomical Society (2010-2014). He is an associate editor of Astronomy and Astrophysics, one of the three major journals in the astronomical community (2018-). He was the director of the Yunnan Observatories of the Chinese Academy of Sciences (2009 – 2015) and the director of the Key Laboratory for the Structure and Evolution of Celestial Objects, Chinese Academy of Sciences (2009-2014). He was awarded the Ho Leung Ho Lee Foundation Prize for Scientific and Technological Progress (2016) and the 2nd prize of the State Natural Science Award (2013).

Topic: Stars in Astrophysics

Abstract  Stars are the cornerstones of astrophysics. In this talk, I will first show how dark matter and dark energy have been inferred to exist.  I then discuss binary evolution leading to the formation of double compact objects, e.g., double black holes, double neutron stars, and double white dwarfs. Those objects emit gravitational waves. I will also show how exoplanets are detected.
KEY WORDS: stars, dark matter, dark energy, gravitational waves, exoplanets
