Calculate the Absolute Visual Magnitude of Cepheid Variables

Calculator

The calculator finds the Cepheid Variable Absolute Visual Magnitude for given pulsation period. Cepheid variable is a star which is used to calculate distances from around 1kpc to 50 Mpc. The absolute visual magnitude is the measure of celestial variable's intrinsic brightness.

Formula:

M_v ≃ -2.76 log₁₀ P_d - 1.40

Where,

M_v = Absolute Visual Magnitude,

p = Pulsation Period
