| 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. |
