1) Is our solar system's angular momentum vector roughly parallel to that of the milky way's?

2) Do we know the orientation of the angular momentum of other Miky way stars and systems...?
Seems like we have imaged a number of proto planetary disks, so we might have the data to make some conclusions...

If most planetary systems are oriented paralell to the galaxy then we should expect to see only roughly edge on views of these proto planetary diske when looking out along the plane of the galaxy, while looking perpendicular to the plane we should see the disks "face on".

The reason I ask is that if a large percentage of solar systems are oriented roughly perpindicular to our own then they will harder by far to be detected by the Doppler method...

Obviously the solar systems we have detected via the doppler method must have some significant component of their angular momentum parallell to ours...

All the planets, and our sun, in our solar system, (the exception being Uranus), have roughly the same direction of angular momentum... I am curious if this carries over to the galactic scale?
