The Merging Star Hypothesis: Following the Curving Path
June 30, 2017
A 3D model of the surface of the merging star painted with temperature. The temperatures range from 5300 K (orange) to 6100 K (cyan) as can be seen from the colorbar at the bottom of the figure.

A star chart of the vicinity near KIC 9832227. The bar on the lower left shows the length of 10 degrees for a scale. (The cross section of a hand held at arm's length measured across the knuckles is about 10 degrees.) Up in the diagram is towards the North Star. If you stand facing south around midnight in July in Michigan and look up, the top of the chart corresponds to the stars directly overhead. The wide triangle of three bright stars (colored white) will be the first thing you notice. The constellation patterns about each of the three can then be discerned. The lines in the constellation Cygnus form a cross (often informally named the "Northern Cross"). KIC 9832227 can be seen to be an extension of the crossbar.
