Calculate the Absolute Visual Magnitude of Cepheid Variables


The calculator calculates the Cepheid Variable Absolute Visual Magnitude for given values.


Pulsation Period:

 

 

 

Cepheid Variable Absolute Visual Magnitude: 

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:

Mv ≃ -2.76 log10 Pd - 1.40

Where,

Mv = Absolute Visual Magnitude,

p = Pulsation Period
