Unfortunately theres no way I know of setting surface temprature...so this will show as 77K when its supposed to be ~35,000 K..
Most of my information came from this website...

thanks,
does a white dwarf really spin that fast?

I read somewhere that it rotates 23 times in a minute...I think it was the website above...

I would suspect that it would spin faster the smaller in size it got just as a skater holds in their arms to spin faster. Makes since anyway. Neutron stars spin extremely fast resulting from being at the center of a super nova explosion and getting "blasted" into a really fast spin.

Hey Ras,
The files not there! I was able to get into your directory and guess what- no sirius.zip is there at all.

Added this info into my "Extrasolar" file. This puts the white dwarf around Sirius spinning at 23 rpm AND gives it the eliptical orbit between 8 and 31 AU (read that somewhere) For the texture, I used Rassilion's texture for an add-on he put together. grab it here.
