Luminosity Calculator

Posted by Dinesh on

Online luminosity calculator to calculate total amount of energy emitted as a black body radiation by a star, galaxy, or other astronomical object per unit time.

Calculate Total Amount of Energy Emitted by a Star

Formula:

L = ? A T4

where,
? = StefanBoltzmann constant [5.670373x10-8W?m?2?K?4],
A = area of the illuminated surface,
T = temperature (in Kelvins),
L = luminosity
