Differential Photometry of variable star with micro variations

Kepler data, sensor pos 41: Search for micro variation variable stars, object 7 8 9 10 11 12 13 14 15 16 17 18 19
Image process tool : AstroImageJ, Irfanview
Processing : Multi aperture analyze
Site : Space
Comment : The T objects are offset along the Y-axis. As you can see they show different wave pattern compare to the reference stars at bottom. I have now sent these data to Hans and Thomas for further analyze.

Now waiting exited if they find some of these star to be unknown. I come back about this in a few days.

With this new data I have two new kind of objects, eclipsing variables and rotation variable star, the latter from big hot spots on the stars surface, as our sun's sunspots. atmosphere.
