Circumbinary Planet Issues

With the number of circumbinary planets that are becoming known getting into the dozens, there's a somewhat niche issue that I would like to bring to the attention of the developers, even if I'm sure they're already aware of it.

Planets orbiting barycenters are assigned temperatures of 0 K, and the barycenters do not show up in the Stars List when set to "planets with stars." The latter seems like it might be an easy fix but the former could be more challenging, I concede.

: Despite being in the Kepler-47 system, Kepler-47 does not show up as the nearest planet-hosting system.

Could you provide test data?

Literally any circumbinary planet. You can download the data I used to create the above screenshot here.

Apparently it was the developers' choice not to show barycenters in the Star Browser (if you mark the option "nearest", they will not show up too). But their planetary companions are correctly registered as their children.

This is very frustrating, indeed.

Oh dear, the good old days when I worked on my fictional ternary star system with planets. I recall the temperature parameter was removed from newer versions of Celestia and indeed the 1.7 built im using doesnt display temperature.

Sirius_Alpha is using 1.6.1/onetwothree's 1.7.0.
Based on the time you became inactive, I am assuming that you use Alexell's 1.7.0, right?

yes, one of his builds, I lost track which one exactly. there are so many unofficial builds floating around. Have there been any improved builds since the new developing team took over?

You can always check the 1.7.0 dev thread, I'm not too knowledgeable in that area so I really don't know.

Even if you want to remove the temperature tag, there's still the problem of the system not appearing in the Star Browser.
