But during the star's formation the distribution of the mass throughout the protoplanetary system might have been much different. And you may regard my question as asking about the correlation of spin and *present-day-technology-detectable* exoplanets.

IN your last sentence you describe Altair as a planet when you shoud write star.

@M.A.Golding Thanks. But please do feel free to edit a question that contains an obvious typo. There is absolutely no need to try to embarass the author by explicitly pointing out the mistake, instead of just making the correction yourself.

Has Altair flung off its planets by rotation?

Or could a passing object have snaked the planets from Altair and simultaneously increased its rotation rate?

No.

There is no mechanism that can transfer angular momentum from the star to a planetary system. The two aren't linked. The spinning of the star doesn't pull the planets forward and "fling" them.

There are some small tidal linking between the star and the planets, but these are not enough to eject planets over the life span of such a star.

Altair doesn't have any *known* planets. It may have planets, but they don't orbit at a distance or be of a size that we are able to detect.
