Maybe you should read the post I made "links for luminosity data". It shows exactly where you can find luminosity data for some stars.
the brightest known Blue Giant is 1,4 million times the luminosity of Sol,
Note that - the brightest known (OI class, blue supergiants). Simply knowing a star is a blue giant is not enough to tell you how luminous it is. As already demonstrated, blue giants can be as low as bellatrix, a BIII (normal giant) star
and the more common type of which are Rigel and Spica is 20 000 times the luminosity of Sol.
Do not confuse "average luminosity" with "luminosity of every star of this type"
from the very same page you linked, by clicking on "Rigel" we can see Rigel's luminosity is 50,000 sol, not 20,000. Similarly, from other sites, we can see
Spica's luminosity is 2,200 sol rather than 20,000 (confirming the link I gave earlier that you don't to see)
How conveniently you use those low numbers from Bellatrix to support your cause.
Of course I do, since my cause is that we don't know enough to conclude which case had the ISDs being bombarded by the most radiation.
Lets take three more stars
Rigel,Luminosity 20000 Sol
Wrong. From your own link, 50,000 Sol.
BTW, Rigel is a blue supergiant (BIa) rather than blue giant. You know that link you gave? It might explain the difference between supergiants and giants
Spica, Luminosity 20000 Sol
Wrong. 2,200 sol (as given in two seperate links I've supplied. Please feel free to give an actual link that significantly contrdicts them)
10 Lacetra,Luminosity 1,400,000 Sol
Wow, a bit higher than Bellatrix aint it?
Assuming you've actually got the correct luminosity there yep*, though that is more likely to be something like a , but then Bellatrix
is a blue giant - specifically class BIII, and thus makes my point nicely.
* 10 Lacetra is apparently the spectral standard for O9V stars, main sequence "dwarf" stars by the page you gave. Maybe you shouldn't be using it in comparison with blue giants after all.(
