Solar Rotation Calculator
Posted by Dinesh onOnline astrodynamics calculator to calculate angular velocity solar rotation from the user input.
What is Solar rotation?
The solar rotation varies with latitude because the Sun is composed of a gaseous plasma. The rate of rotation is observed to be fastest at the equator (latitude φ = 0 °), and to decrease as latitude increases. At the equator the solar rotation period is 24.47 days and almost 38 days at the poles.
Angular Velocity of Solar Rotation Calculation
Formula:
ω = A + B × sin (ϕ)² + C × sin (ϕ)⁴
where,A, B, C = constants
ϕ = solar latitude
ω = angular velocity
A current set of accepted average values
A = 14.713 ± 0.0491 °/d
B = -2.396 ± 0.188 °/d
C = -1.787 ± 0.253 °/d
