Re: Extrasolar Planets (updated catalogue)

Do you have a reference for the size of WD 1145+017 "b"? All the literature I've seen suggest there are numerous objects with unknown size, whose existence is known only from the transits of their evaporating debris clouds.

Re: Extrasolar Planets (updated catalogue)

TESS Sector 14 planets are out! And it contains the Kepler field, too. TOI-1172 appears to be broken on ExoFOP's end. TOI-1232 has two different candidates listed as TOI-1232.01, and I'm not sure if this is just a glitch or what. I will wait for them to fix these two on their end, though if they hav...

Re: Celestia 1.7.0 Development Thread

Yeah I experimented around with this a little, putting a tiny invisible planet in a polar orbit in such a long period that it's "stuck" over the north/south pole of the star, so that the planet doesn't cast a shadow on the ring. They kinda look nice but if you're viewing them the "wro...

Re: Celestia 1.7.0 Development Thread

Kinda off-topic but is it possible we could have rings around stars, too? They would need to have some sort of Emissive True property as well as a much greater visibility distance. This might enable the implementation of circumstellar disks.

Re: Spacecrafts for Celestia

I'm not sure I understand exactly what you mean. Are you saying that because the inclination change was performed at apoastron, you think the data is suspecft? If so, it turns out inclination changes occur best at lower orbital velocities. Inclination changes at apoastron are much more fuel-efficien...

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

Re: Extrasolar Planets (updated catalogue)

TESS Sector 13 planets are out! BD+04 701 is a (visual?) binary system with a TESS planet candidate around each star. I don't have data right now on the system to render it as a binary, rather than as two separate single stars. Though with as interesting as this is it'll probably be the target of la...

I've been seeding the torrent for over a while now and have reached a ratio of 2.207. I'll keep it going for a few more days. That should push up the download rate.

Re: Object Comparison

Is this an issue? Or a silly mistake of mine? The issue arises in the way Celestia calculates the "distance." For a planet, the distance is between the observer and the surface, whereas for a star, it is defined with respect to the centre of the star. If you "land" on the star's...

Re: Custom colors in Celestia would make it more beautiful

You have the full capability to define a custom texture for your star in the .stc file for it. Otherwise, you can replace the textures (astar.jpg, bstar.jpg, ostar.jpg, etc...) with some that you like.

Re: Seeking spam protection posibilities

I admin an exoplanet forum , and from my experience, the best way to deal with the problem is to do manual user-account activation. When users sign up, you can see their e-mail addresses. It's often pretty clear which e-mail addresses are "real" and which are spam bots. Something like khow...

Re: 1K and 2K textures. Is it necessary nowadays?

The lower resolution maps seem to take up such little hard-drive space (especially in the 2010s) that I'm having a hard time justifying the trade-off of getting rid of them at the expense of people with lower-end computers.

Re: Celestia crashes ~120 Light Years away from binary star

I think the crashing issue was something else. I had some barycenters missing any IDs. They crashed the programme whenever you got too close to them. 11 Com and DP Leo were just along the line of sight to systems that were incorrectly declared, so they were themselves not at all the problem. Barycen...
