Rotational Velocity of Star Calculator

Online calculator to calculate rotational velocity of star. The equator of star will have a rotational velocity of 317 ± 3 km/s. This corresponds to a rotation period of 15.9 hours which is 86% of the velocity at which the star would break apart. The equatorial radius of this star is 32% larger than polar radius. Enter the space velocity and tangential velocity in the below rotational velocity of star calculator to get the resultant value in km/s.

Formula:

Rotational Velocity (Rv)= √(a2 - b2) Where, a = Space Velocity b = Tangential Velocity

Example:

Calculate rotational velocity of star for space velocity as 9 km/s and tangential velocity as 8 km/s.

Solution:

Rv = √(92 - 82)
= 4.1231 km/s
