Research on Lunar Eclipses in the Yin Period Oracle Bone Inscription Based on Modern Astronomical Planetary Ephemeris

There are five lunar eclipses with the heavenly stems-earthly branches dating in the Yin period oracle bone inscription, which are the most conclusive materials known for astronomical dating during the period of the Shang dynasty. The Xia-Shang-Zhou Chronology Project has given the date of occurrence of these lunar eclipses. The authors uses the DE422, modern astronomical planetary ephemeris released by NASA's Jet Propulsion Laboratory (JPL) to calculate main parameters of these lunar eclipses and study their observations on the Earth. The visibility of these lunar eclipses in Anyang, capital of the Shang dynasty, is further confirmed. The results support the date of theses lunar eclipses given by the Xia-Shang-Zhou Chronology Project and provide a certain reference for the in-depth study of the lunar eclipses in Yin period oracle bone inscription.
