# period of an eclipsing binary

I am confused about the definition of the period of an eclipsing binary, a binary configuration where one component crosses the other across the line of sight. When people say that an eclipsing binary has a period of T years do they mean that the period of the individual component is T years?

• No idea where your confusion could be? Both components orbit the centre of mass with the same period. Jul 28, 2016 at 17:48
• In binary star configurations, both stars orbit each other with the same period. When they say the eclipsing binary has a period of T years, they mean that both stars complete one orbit in T years and that implies that the eclipse will occur every T years. Jul 29, 2016 at 17:40
