| 英文摘要 | We characterize the morphology of the photometric phase curve model of an asteroid with a three-parameter magnitude phase function H - G(1) - G(2) system by considering the effect of brightness variation arising from a triaxial ellipsoid representing the asteroid's shape. Applying this new model and a Markov Chain Monte Carlo method, we refine the photometric phase curve of asteroid (107) Camilla and obtain its absolute magnitude H = 7.026(-0.054)(+0.052) mag, and phase function parameters G(1) = 0.489(-0.044)(+0.043) and G(2) = 0.259(-0.023)(+0.023). Meanwhile, we also determine (107) Camilla's orientation of pole (74.1 degrees(-4.5)degrees(+4.3 degrees), 50.2 degrees(+5.4 degrees)(-0.060)) with rotational period of 4.843928(-0.000001)(+0.000001) h, and axial ratios a/b = 1.409(-0.020)(+0.020) and b/c = 1.249(-0.060)(+0.063) Furthermore, according to the values of phase function parameters G(1) and G(2) we infer that asteroid (107) Camilla is an X-type asteroid. |
