| 摘要 | Mutual events between natural satellites include mutual occultation and mutual eclipse. Mutual eclipse is another kind of mutual occultation as viewed from the center of the Sun instead of the Earth. Two mutual eclipses of J2 Europa by Ti Io (2009 Aug. 28 and Sept. 12) were observed at Yunnan Observatory during the PHEMU09 international campaign. We will calculate the astrometric data of these Galilean satellites by analyzing and fitting the light curves we obtained. The limb-darkening was considered during modeling the light intensity of eclipsed satellites in the penumbra zone, by taking the Lommel-Seeliger scattering law into account. Several dynamical quantities, such as the relative coordinates of the eclipsing satellite from the eclipsed one Delta alpha cos delta and Delta delta, impact parameter and mid-time corresponding to the impact parameter and the deviations O - C of observed Delta alpha cos delta and Delta delta relative to ephemerides, were obtained for each event respectively. |
