Photometry & interferometry of nearby secondaries

To improve the statistics of hierarchical multiplicity, secondary components of wide nearby binaries with solar-type primaries were surveyed at the SOAR telescope for evaluating...为完善分层多重性（hierarchical multiplicity）的统计数据，研究团队使用SOAR望远镜（SOAR telescope）对主星为类太阳恒星的近距宽双星的次级伴星开展了巡天观测，以评估……
