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: How to modify names of existing/built-in stars

The following adds V376 Peg to HD 209458.

Code: Select all

Modify 108859 "V376 Peg" # Modify, HIP if present, name desired to add.

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...

Celestia crashes ~120 Light Years away from binary star

I've been working on automatically generating binary stars and I've developed a bit of a problem. A couple systems -- 11 Com and DP Leo (and probably numerous others) cause Celestia to crash whenever you get some distance away (a bit over 120 light years in the case of 11 Com). This problem occurred...

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 ...

Re: Hyperion Proto-supercluster

I always thought galaxies in Celestia were much too bright. The "pretty picture" images that you're invoking are long-exposure images, rather than anything remotely close to what the human eye sees. Only the very centre of the Andromeda Galaxy is visible to the naked eye from Earth, nothin...

Re: Extrasolar Planets (updated catalogue)

TESS Sector 12 planets are out! And a lot from prior sectors. 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'l...

Re: Celestia 1.7.0 Development Thread

If you all are taking requests for 1.7.0, could I make a minor one?

Can T dwarf atmospheres be removed (or changed)? Their atmospheres are black, making transiting T-dwarfs look strange (example image attached).

Re: Extrasolar, Stars and Exoplanets for Celestia

It's perfectly plausible for a tidally locked planet to have significant heat redistribution to the night side via its atmosphere. Not all tidally locked worlds will have such dichotomoes. And if you don't believe me, consider the fact that Venus' surface temperature is effectively constant between ...

Re: Extrasolar Planets (updated catalogue)

01 July 2019 TESS Sector 11 planets are out! -- at least the first batch of them. See prior update for involved caveats. Also there are some new TESS planets from previous sectors. Teegarden's Star has planets of course. Thanks to some assistance from Fabers_br , I've implemented correct transit tim...

Re: Extrasolar, Stars and Exoplanets for Celestia

Just FYI, the orbital parameters for Wolf 1061 have been significantly updated by Tuomi, et al.'s paper posted a few days ago (link). The outermost planet especially has a shorter, more circular orbit.

Re: Extrasolar Planets (updated catalogue)

My only concern about that is the eventuality that a planet will be discovered around such a star. Of course 30 Ari A is too tight a binary for this to actually occur, but if for example a planet were to be discovered orbiting 30 Ari Aa, what do you call it? Aab? That being said, I do recognize that...

Re: Extrasolar Planets (updated catalogue)

TESS Sector 10 planets are out! -- at least the first batch of them, it seems that they come out in smaller groups after an initial large release. Furthermore, a lot of new planets in very nearby systems was reported (Wolf 359, Lacaille 9352, Struve 2398 to name a few). So there's plenty of reason t...

Re: Variable Stars in the Hipparcos Catalog

The best I know how to do is doing a SIMBAD criteria search for

Code: Select all

cat = 'HIP' & cat = 'V*'

I have attached an .xlsx file with the results of this search but there are only 6,948 entries.
