Albedo heterogeneity on the surface of (1943) Anteros
摘要：
我们研究了旋转对近地小行星（1943）Anteros散射光偏振的影响，使用夏威夷大学的2.2米望远镜的双光束成像偏振计。安特罗斯是一颗L型小行星，以前没有被偏振观测到。我们发现微弱的，但显着的变化，作为一个功能的旋转的极化安特罗斯，表明整个表面的变化。具体地说，我们发现Anteros的背景反射率为p_v = 0.18 +/- 0.02，其中p_v < 0.09的暗斑覆盖了< 2%的表面。
英文摘要：
We have investigated the effect of rotation on the polarization of scattered light for the near-Earth asteroid (1943) Anteros using the Dual Beam Imaging Polarimeter on the University of Hawaii's 2.2 m telescope. Anteros is an L-type asteroid that has not been previously observed polarimetrically. We find weak but significant variations in the polarization of Anteros as a function of rotation, indicating albedo changes across the surface. Specifically, we find that Anteros has a background albedo of p_v = 0.18 +/- 0.02 with a dark spot of p_v < 0.09 covering < 2% of the surface.
