As it was mentioned in another thread, you will find most (all?) suns looking some sort of white to you when looking frome closed up. So a white core with a tinted coronaic glow would probably more the kind of look you are supposed to have in real - not those colored bubbles you have now.
The human eye is hugely tolerant of spectral drop-outs, since it only has three colour receptors, each of which responds to a broad range of wavelengths - remember that even the spectrally crippled output of the coloured phosphors on your monitor screen can fool your eyes into seeing white.chaos syndrome wrote:Hmm, would this appearance of white apply to carbon stars as well - as I understand it there are significant wavelengths missing from the spectrum...
Although the spectrum is filled with C and N emission spikes, they wouldn't be that noticeable, I think (see above for the relevant argument). So a black body of around 50000K might roughly fit the bill: [0.53 0.64 1.00] on my Dell monitor. This is pretty robust for the range of predicted temperatures for Wolf-Rayets, since the high frequencies of the black body spectrum are close to being an exponential curve, which is pretty much self-similar whichever part of it crosses the visible range: 100000K comes out at [0.50 0.62 1.00], for instance, which doesn't look at all different to 50000K.chaos syndrome wrote:Checking through the source files it seems the colour of Wolf-Rayet stars would be quite easy to add (if you had a suitable compiler) - is there any idea what a suitable colour would be?

Can we not just use alternate textures for stars?

The spectroscopic idea is really fascinating, but is probably far off, no?
Firdiger, would you be willing to make a couple of alternate textures from the pictures you keep teasing us with, in the interim? It wouldn't take long, and I always thought having that red "magma" texture would be better than having the sun look like verything else.
Once Celestia can vary my view across wavelengths, Celestia will be better than real life!
My only comment involves the size of the sunspots. The star textures in Celestia have GIGANTIC sunspots. Is that real? I thought sunspots were relatively small (dots really). Every time I look at a photo of the Sun in visible light, the sunspots are tiny dots.
