The Yunnan Observatory of the Chinese Academy of Sciences first discovered the existence of quasi-periodic oscillations in the light variability of a nova

On October 14, the reporter learned from the Yunnan Observatory of the Chinese Academy of Sciences that researchers recently discovered for the first time in China that there is a quasi-periodic oscillation in the light variation of a quasi-nova, and at the same time confirmed that there is a strong wind in such a system.”Astrophysical Journal”, the relevant results are of great significance to the study of the accumulation and evolution of binary stars.

Astronomers in my country discovered for the first time that there is a quasi-periodic oscillation in the light change of a nova

The reporter learned from the Yunnan Observatory of the Chinese Academy of Sciences on the 11th that for the first time, researchers at the station discovered that the light variation of quasi-novae has quasi-periodic oscillations, and confirmed that there are strong disk winds in such systems. The relevant results are useful for studying the accumulation and evolution of binary stars. It is of great significance.
