In the light curve below, what is the period of the eclipsing binary?

Question

Quizplus · Accepted Answer

The period of an eclipsing binary is the time between two eclipses of the same type (primary or secondary). In this light curve, we can see that the primary eclipses have a depth of around 1 mag and occur every 32.5 days, while the secondary eclipses have a depth of around 0.6 mag and occur about halfway between the primary eclipses. Therefore, the period of the eclipsing binary is 32.5 days. The period of an eclipsing binary is the time taken for one complete cycle of the light curve, which includes both the primary and secondary eclipses. From the light curve, we can see that there are two primary eclipses and two secondary eclipses within the span of approximately 65 days. Therefore, the period would be half of that, which is approximately 32.5 days.
