Talk:Epsilon Canis Majoris

Absolute Magnitude of the companion

How is it possible that the dim companion of ε Canis Majoris has absolue magnitude -5.0 while the brighter one has only -4.1? Since they are at the same distance from Earth and the Luminosity ratio is 1:250, the dimmer star should have absolute magnitude around +1.9. Easy n (talk) 22:20, 2 January 2009 (UTC)

I agree. The absolute magnitude is 7.5 + 5(log( 0.00757 ) + 1) = 1.9. I modified the article.—RJH (talk) 18:52, 9 April 2010 (UTC)
