Binary Systems - The Solution
- When would you expect the brightness of the small star to be greatest?
In an eclipsing binary, the brightness of the smaller, brighter star
is greatest when its companion star, in this case the dark colored
ball, is behind it.
- How do you think the stars will be arranged when the combined
brightness of the system is faintest?
A binary system would appear faintest when the dark colored ball or dim star
passes in front of the smaller star to completely cover it's brightness.
