KIC 8462852 | Asymmetrical U-shaped Dips Similar to Expected Shape for Evaporating "Planet"?

  • ianhenderson by ianhenderson

    Hi, all,

    I read this article today and noted the similarity of the asymmetrical U-shaped dip of a planet being 'vaporized' by its white dwarf host star, and the asymmetrical dips present (albeit MUCH larger) in KIC 8462852:

    Take care,

    No they are very different. It does however (unsurprisingly) bear resemblance to KIC 12557548.

    As whatever is happening with KIC 8462852 is not repeating on short timescales, then clearly it is not close enough to the star to be being vaporised.

    Forgive me, I'm not sure I worded that very well (and we may be at cross purposes).

    I am aware that the large, asymmetrical dip is consistent with something very big and very distant from the star.

    I'm wishing to comment that I find the asymmetry puzzling as the only cause I am aware of for an asymmetrical dip is when a planet is very close to the host star and is being vaporized. This is clearly not the case in KIC 8462582.

    Does anyone have a handle on why the large dip is asymmetrical around the central, dip? (I'm not asking about the other, smaller dips which appear around it; just the large, central, dip.)

    What about something like this? Possible explanation? https://www.dropbox.com/s/v2h8x0nst61dm89/KIC anomaly.jpg?dl=0
