This star is actually a binary system and has a circumstellar disk.
I only point this out since this star is the one spend alot of my time on.
I f I had the ability I'd make a replacement, but not quite sure how to procced.

In Celestia v1.4.0 or later, you can replace Stars by Barycenters and place Stars in orbit around them. A description of the new STC STar Catalog declarations is on the Web page http://www.lepp.cornell.edu/~seb/celest ... eters.html
Examples are in Celestia/data/nearstars.stc and Celestia/data/visualbins.stc
Hopefully you can locate the orbital parameters.
A spreadsheet to translate from orbital parameters measured on the sky into Celestia's orbital parameters is on the Web page http://www.lepp.cornell.edu/~seb/celest ... ets.html#2
