The planet of Aurei has a binary star system with two heartbeat suns. It also has one tidally locked moon that behaves like Earth’s moon.

The two suns do not rise at exactly the same time. The larger sun rises first, followed by the smaller one. The larger one also sets before the smaller one.

The following diagram displays the various sunlight phases in Aurei.
