名詞

Trojan test (plural Trojan tests)

1. (astronomy) A test of binarity. A test to determine if a two-body system is a primary and satellite, or a binary system. A test to determine if the L4 and L5 Trojan points (Lagrange points) are stable or not. If it is determined they are stable, the system is that of a primary and satellite. (where one component is at least 25x times more/less massive than the other) If the points are not stable, then the system is that of two components in a binary relationship. (where the two components have less than 25x the difference in mass with the other)
   1. The mass ratio of 1:25 or 25:1 diving line for the existence of stable Trojan points, marking the divide between binary systems and primary-satellite systems.
