Added Sirius B if anyone wants the code...

Save to the extras directory in your Celestia folder and run...

All data is an approx. of what is therized to be Sirius's companion white dwarf...

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?

[Rassilon]

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.

I deleted it along time ago Chris will have it in the next version of Celesia already set up I suspect...His version tho...

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. http://cybermindtraveller.freewebspace. ... d-last.zip
