Luminosity of Stars Calculator

Posted by Dinesh on

Online luminosity astronomy calculator to calculate total amount of energy (brightness, temperature) emitted by a star, galaxy, or other astronomical object per unit time using luminosity stars temperature formula.

Luminosity Spectral Class
Spectral TypeTemperatureColor
O30,000 - 60,000 KBlue stars
B10,000 - 30,000 KBlue-white stars
A7,500 - 10,000 KWhite stars
F6,000 - 7,500 KYellow-white stars
G5,000 - 6,000 KYellow stars (like the Sun)
K3,500 - 5,000KYellow-orange stars
M< 3,500 KRed stars

Calculate Total Amount of Energy (Brightness, Temperature) Emitted by a Star

Formula:

L = [4?d2b]

where,
? = 3.142857142857143,
d = distance,
b = Brightness,
L = luminosity of the star
