The upper limit of 14 km/s for the equatorial rotation velocity is equivalent to a rotation period of 3 days.

For stars in this range, the measured rotation velocity increases with mass.

The projected rotation velocity is 1.0 km/s, and the chromosphere has a low level of magnetic activity.

It would be extremely interesting to establish a relation between the extent of this zone and the rotation velocity and/or the magnetic field of the star.

Due to the rotation velocity of the receiver, the absorption frequency decreases if the transverse Doppler effect exists.

It is also undergoing differential rotation in which the rotation velocity varies by latitude.

In support of this theory it has been noted that the variations in magnetic field are inversely correlated with the rotation velocity.

The primary has a projected rotation velocity at the equator of less than 3 km/s.

The secondary has a rotation velocity of 7.7 1.7 km/s.

Far as need for decel goes," he said, "yes, sure, we have rotation working against us, but orbital velocity with us.
