Oh thanks! And in the apparent magnitude equation: Apparent Magnitude = -2.5log10(I k) Is k the Boltzmann constant? 1.380649×10−23? I plugged in the sun’s Intensity (1360 w/m^2) and only got -7.84 instead of -26.74 Not sure why it came up with the wrong answer And furthermore, what about the...

Oh thanks! So if I understand you correctly, the Stefan-Boltzmann equation gives you the power emitted per square meter on the surface of the star, while I is the power received per square meter on a larger sphere surrounding the Star with a Radius equal to the distance between the center of the...

So I guess intensity is the same as luminosity which does depend on radius? Or was the source wrong to include intensity in the apparent Magnitude equation? But then what about the part of the star’s energy that is emitted in the opposite direction (since it is a sphere)? Wouldn’t that be part...

This doesn’t seem right... maybe my source meant to say intensity is the same thing as luminosity and not energy flux per unit surface area? Idk it’s confusing stuff to learn without worrying about bad sources.

For a star.. Apparent Magnitude = -2.5log10 I K And I = I0/d^2 So in terms of I0... Apparent Magnitude = -2.5log10 (I0/d^2) And the Stefan-Boltzmann law says: Energy Flux = Sigma(T^4) In my reading it says that Intensity is the energy emitted per unit of area per unit of time. It says the same...
