The Try of an Explanation of the Dip at day 792
|Fig 1: The dip at day 792 has a very interesting homogenous shape.|

The most simple model
To generate the situation, we start with a very simple model. A long beam from the star points radially away from the center of the star. by accident, we are in the line of sight and see the beam crossing the star.
|Fig 3: Simple model, a beam of matter, pointing away from the star.|
To describe this model, we assume, that the beam is rotating around the star and a fraction of the beam absorbs the starlight on our line of sight.
|Fig 4: Geometric situation, Kepler looks from the right side to the star with center C.|
The star has a radius of r and the center is marked by C, a beam with an optical density d, at the surface of the star starts at point A and ends at point D. The dimming is proportional to the length, of the distance |AB|, because only this part of the beam covers our line of sight. We can calculate the distance CB, depending on the angle a, it is
