About Me

中文 | English

Introduction

My name is Guoyou Sun. I go by G. Sun or G. -Y. Sun for short. Sun is my surname and Guoyou is my given name. Chinese names are written in surname-first order. Hence, my name should really be written as Sun Guoyou (孙国佑 in simplified Chinese, 孫國佑 in traditional Chinese). 

I was born in 1984 in Yueqing City, Zhejiang Province, People’s Republic of China. As an amateur astronomer, I’m passionate about discovering new celestial objects and am a proud member of both the Chinese Astronomical Society and the Xingming Observatory Sky Survey team . Notably, I am one of the co-discoverers of the famous luminous red nova V1309 Sco, often referred to as the “Rosetta Stone” for understanding stellar mergers. I also led the team to discover the first light of the nearby supernova SN 2023ixf. The related achievements were published in the journal Nature. In recognition of my work, I was awarded the 2015 Edgar Wilson Award for the discovery of Comet C/2015 F5 SWAN-Xingming. It is an honor to have an asteroid named after me, designated  (546756) Sunguoyou. and I have accomplished a grand slam in the discovery of celestial body types and hold the record for the most discoveries of new celestial body types in the world.

 

Grand Slam of astronomical discovery

I have discovered hundreds of new celestial bodies. Including comets, asteroids, near-earth asteroids, exoplanets, supernovae, novae, luminous red novae, nova-like stars, dwarf novae, young stellar objects, active galactic nucleus, brown dwarfs, eclipsing binaries, pulsating variables, eruptive variables, rotational variables, X-ray variables, strong gravitational lens, microlensing events, multiple star systems, planetary nebulae, HII region, open star clusters, double stars, and so on.
