Photometric properties of asteroid 8050 Beishida

The physical properties of asteroid such as albedo, shape and pole determination can be figured out by analyzing the light curves of the asteroid．In this paper, photometric data observed by the 85 cm telescope at Xinglong Station of NAOC (National Astronomical Observatories, Chinese Academy of Science) and 50 cm telescope at Yading Station of CASYO (Chinese Academy of Science, Yunnan Observatory) were used to obtain physical properties of Asteroid 8050 Beishida, by adopting disk-integrated brightness model of Lommel-Seeliger scattering ellipsoid based on Monte Carlo-Markov chain method．The ellipsoidal parameters of Beishida were found to be (5.140 ± 0.010) , ( 1.698 ± 0.004) , ( 1.077 ± 0.004)km; the spinning period was (5.397 ± 0.003)h; the geometric albedo was 0.195 ± 0.001; the phase parameters were G₁ = 0.259 ± 0.002 and G₂ = 0.373 ± 0.001, respectively．The ecliptic coordinates of pole determination were found to be (104.68°/284.68°, ±80.06°)．
