• New progress in seismological research of mixed main sequence variable stars at Yunnan Observatory

    Recently, Dr. Chen Xinghao and researcher Li Yan of the stellar physics group of Yunnan Observatory cooperated with researcher Zhang Xiaobin of the National Observatory to accurately obtain the central convective core scale of the mixed variable star Corot 100866999 in the main sequence evolution stage by using the method of astroseismology. The research results were published in the Astrophysical Journal on December 26 On the herogram, the hybrid variable is located in the overlapping region of the instability zone of delta variable in shield and gamma variable in swordfish,…
