Interesting star (3-phase AC pattern)

  • waldwatz by waldwatz

    can someone give an explanation how this works ?

    if it isn't an error in the data, what causes this geometrical patterns ?
    for me it looks like the curve i know from 3-phase AC.
    i thought about an eclipsing binary but this doesnt fully makes sence for me.

    and as noone who spotted this by now came up with a good explanation ....

    maybe someone a little more experienced could help me out with an explanation. i want to learn about it 😉

    Kepler measures the brightness of each star every 29.4 minutes. In this case the period of the eclipsing binary is by chance close to an exact multiple of this interval, so that the three or four measurements which coincide with each eclipse are similar to the previous eclipse but only very slightly offset each time. The result is this pretty geometrical pattern. Check out this paper for various other patterns in the light curves of short period eclipsing binaries.

    that sounds like a reasonable Explanation. thank you
