    Yes, that why I call it the enhanced Yarkovsky effect. It is not just re-radiated solar energy, but ejecting particles because of it, It has even been called a kind of "comet" because of it. Even the slight irregularities of Halley's have been attributed to the effects of radiation during rotation. Oumuamua is a prolific rotator, tumbling in all three axes.
    My speculation is that gravity acts in a slightly different way in the plane of the ecliptic then above and below it, where the visitor is heading, although the solar system is not a full disk like a spiral galaxy.
