Magnitud estelar<br />

Para dos estrellas con intensidades radiantes E1<br />

y E2, la diferencia de magnitudes visuales m1 –<br />

m2 puede ponerse como:<br />

m1 – m2 = - log 2,512 E1/E2 ⇒ E1/E2 = 2,512 -(m1-m2)<br />

y en logartimos decimales:<br />

log (E1/E2) = -0,4(m1-m2)<br />

⇒ (m1-m2) = -2,5·log(E1/E2)
