Light curve of the week: tidally distorted EB
(200 words excerpt, click title or image to see full post)

This week we have an EB where the two stars get so close to one another that their gravitational pull distorts their shapes, changing it from a sphere to a rugby-ball type shape. The increase in surface area from this results in an increase in observed flux after the primary eclipse. If you look carefully you can also see a small secondary eclipse!
