Placing a ship in deep space independent of a solar system

[Hungry4info]

Spectral Types: (hottest to coldest)
O B A F G K M L T Y

O -> Blue
B -> White-blush
A -> White
F -> Yellow-white
G -> Yellow
K -> Orange
M -> Red-orange
L -> Red
T -> Dim red
Y -> Planet-like

O through M are on the main sequence (burning hydrogen). L and T are brown dwarfs, and Y is a sort of transition between brown dwarfs and planets. Spectral type T is so cool that it is not drawn with a visible atmosphere or flare in Celestia (which is reasonable).

The numbers further specify temperature. 0 is brightest, 9 is dimmest.
G2 stars are yellow, and are relatively bright for the class.

The roman numeral afterward is a luminosity class.
VI -- subdwarf
V -- Dwarf (Like our sun).
IV -- subgiant
III -- giant
II -- bright giant
I -- Supergiant


Thus, a T9V star is very cool brown dwarf, the dimmest of the T-type stars, and is a dwarf. In Celestia, it would appear only as a emissive true sphere. (Open Celestia, search "2MASS" and you'll get several brown dwarfs, some of them will be as I describe).

Very nice! Thank you. Looked like a glowing gas giant.

I'm sure that will be useful.

Reiko,

You're very welcome, of course.
I reported the crash in Celestia's SourceForge bug tracker.

Reiko and Selden,

Thanks for reporting the bug. The fix was extremely simple and has been committed to SVN in revision 4559.

Works perfectly! Don't even need to change the diffuse levels of the model now. Thanks!
