This anything interesting? Significant dips in brightness

  • Pulsuhundur by Pulsuhundur

    This star came up for me earlier: http://talk.planethunters.org/#/subjects/APH0000zch?quarter=1-2

    It shows significant dips in brightness, ranging from around 10% down to as much as almost 27%.

    So it's obviously an Eclipsing Binary. Typical alternating eclipse depths as well.

    Yeah, I noticed that the ~20% and the ~27% drops are consistent and figured that it was an EB, but in Q1-2 there's a ~10% drop that doesn't show again.

    You mean the one at BKJD 2262.77? It's just a distorted version of the secondary eclipse. Note the upwards "wings" on both sides of the eclipse. This happens relatively often because of the correction algorithm used to counteract the spacecraft movements (mainly thruster firings).
