    I wonder how much clouds and things like that in Neptune's atmosphere affect the readings. Seems like Uranus, which is blander would be more consistent.

    Sound thinking but a point in favor of using Neptune is that it is further away than Uranus and so serves as a better proxy for the Sun as a distant stellar point. Using Kepler to do the calibration is going to require the object be as stellar as possible. Non uniformity due to clouds will be a smaller effect and the oscillations take place on such a short time scale there won't be much contribution.

    PS Since the time scales of nonuniformities in Neptune's atmosphere are much longer than the variations in Solar flux, they'll not introduce significant errors.

    Ingenious!

    A bit sad that they couldn't predict the mass and size of our closest star within standard deviation, but pretty damn close!

    It indicates that the seismic model used for Kepler analysis needs tweaking. An opportunity to improve is never cause for sorrow.
