A catalogue of multiplicity among bright stellar systems
We consider the multiplicity of stellar systems with (combined) magnitude brighter than 6.00 in Hipparcos magnitudes. We identify 4559 such bright systems (including the Sun), and the frequencies of multiplicities 1, 2, …, 7 are found to be 2718, 1437, 285, 86, 20, 11 and 2. We discuss the uncertainties, …
