Random Science Poll- Sept 4

What is your favorite star temperature type in the Henry Draper Catalog system?

The colors are approximate. Deal with it.

O: 100,000 - 30,000K (White dwarf or Very blue)
B: 25,000 - 12,000K (Blue)
A: 11,000 - 8,000K (Blue-white)
F: 7,800 - 6,200K (White)
G: 6,000 - 4,600 K (Yellow-white)
K: 4,900 - 3,350 K (Yellow-Orange)
M: 3,400 - 2,600 K (Red-Orange)

B, because it is the first letter in Bedtime.

Hmmm... It depends.

If I feel like vegetating, I prefer G. Around 5500K, actually.

However, if I feel like blossoming.. I prefer M. Maybe even an added option N, because I prefer 2.1K in this case.

WTF?

The interesting thing about blue stars is that they burn so intensely that they burn themselves out in a couple million years.

This is interesting if you're wondering why green gets the shaft:
-
So, a high temperature star (say surface temperature 8000 Celsius) will have a black body spectrum that peaks in the blue and will look blue. A low temperature temperature star (4000 C) will have a black body spectrum that peaks in the red and will look red. However an intermediate temperature star that has a black body spectrum that peaks in the green (and there are some) will not look green. why?

This has to do with the way that the human eye perceives color. The human eye uses 3 different type of cells (called cones) in the retina which respond to different colors. Now recall that even though a black body spectrum may peak in the green, this is mixed with other colors (red and blue). It turns out that the specific mix of colors given off by a black body spectrum that peaks in the green is interpreted by our retinal cones as yellow-white. Since there are no star that emit pure green without the other wavelengths, there is no such thing as a green star.

A, I have always liked that blue-white color.

 

[hdeck]

i must have slept through this part of science class.

 

[Hayabusa Rider]

I'm partial to Wolf-Rayet stars myself.

 

[Beattie]

G because that's the star class of the sun
