Abstract:
Planetary nebulae (PNe) are descendants of the low- and intermediate-mass
stars, which account for the majority of stellar populations in the
universe.  As an important category of the interstellar medium, PNe are
one of the few classes of celestial objects that are active in every part
of the electromagnetic spectrum; they have proven to be excellent
laboratories for various basic astrophysical processes.  Today the more
in-depth investigation of PNe requires cutting-edge instrumentation.
I will give a talk based on my research on PNe using the world-class
telescopes, including the Hubble Space Telescope (HST), the 10.4m Gran
Telescopio Canarias (GTC), and the 3.6m CFHT.
 
个人简介:Dr. Xuan Fang obtained his PhD in astrophysics at Peking University
(PKU).  From 2013 to 2016, he was a postdoctoral researcher at the Instituto de
Astrofisica de Andalucia (IAA-CSIC) in Spain.  From 2016 till now, he is
a postdoctoral fellow at the University of Hong Kong (HKU).  He is an
expert on the formation and evolution of planetary nebulae, in both
theories and observations.  As the principal investigator, Dr. Fang has
been awarded and completed nearly 140 hours at the 10.4m Gran Telescopio
Canarias (GTC, La Palma, Spain), the largest single-aperture optical
telescope on earth.
