The names are not made offical by the Astronomical Society yet, but may be proposed for the following Centaurian Planets:
Which 'Astronomical Society', and can you state your sources where you found these many planets?

About the "Astronomical Society"- I was referring to International Astronomy Union (IAU) on https://en.wikipedia.org/wiki/Internati ... nomy_Union. The suggested names for Centaurian planets came from a short article of "Alpha Centauri Bb: Why Are New Planet Names So Dull?" on http://www.bbc.com/future/story/2012110 ... es-so-dull.
* I got Chiron from Sid Meier's Alpha Centauri game.
* I got Ares, Phadora, Domatholos from James Cameron's Avatar Science Fiction series.
* I got Caladan and Arrakis from Frank Herbert's Dune Science Fiction series.
* There is a name of Feronia suggested for Proxima b on https://forum.kerbalspaceprogram.com/in ... a-centauri. I got rest of information from my private dream journals I wrote about precognitve dream trips I had to nearby exosolar systems in our solar neighborhood, in addition to nine planets in our own Solar System few years ago.

What I want to know is where you got the idea from the many planets for the Alpha Centaury system. If you have them out of your 'dream journals', they do not belong in this thread.
This thread is for real exoplanets only.
You can create your own thread for it. And for other objects from your dream journals.

JackDole's quote: "Here you can publish scripts for new exoplanets. This thread is only for real objects."
My apologies...now I understood that I cannot publish any imaginative or unknown worlds here that are NOT discovered yet, nor from the dreams, in this thread but in a separate thread. Thank you for explaining a rule very clearly to me. I shall concur with it.
"Twin Earths Discovered for Alpha Centauri B?" may be found on the NEW SCIENTIST website's:  https://www.newscientist.com/article/dn ... tar-system.  Both of those two exoplanets are very hot like Venus and closest to the primary star. Gravitational tidal forces of Alpha Centauri triple star system can easily explain the total absence of giant gaseous planets like Jupiter there- from the SCIENCE article on https:// http://www.sciencemag.org/news/2018/04/ ... st-stellar. Some of Earth-like exoplanets may be inhabitable considering very low x-ray emission of Alpha Centauri companion stars A & B....see an article "Planets Orbiting Alpha Centauri Stars Not Bombarded By X-Ray Radiation Hazardous To Life" on https://www.techtimes.com/articles/2298 ... us-to-life.

The scripts for the Pulsar contained a bug. I corrected it. (Hopefully.)

JD, is that a real planet? I see no mention of it here:

https://en.wikipedia.org/wiki/SWIFT_J1756.9-2508

Just the remnant of a former companion star?

Also JD have you made a pak of the new pink/purple dwarf planet that was recently discovered?

It may be a former companion star that has been stripped down onto planetary mass.

Actually, these planets should be in the habitable zone, but in SpaceEngine they are a bit too cold.

Teegarden's planets v2

Here is a version with slightly better temperatures. Instead of 'AbsMagn' (absolute magnitude) I use the 'Lum' value (luminosity) for the star.
Teegarden's c has a pretty good temperature.
scr00024.jpg
But Teegarden's b has a more Venus-like temperature and atmospheric density.
scr00025.jpg
However, SpaceEngine makes an 'Oceania' of it. I do not know how realistic that is!

 is this for both .980 and .990?
It does not work with SE 0.980!
It should work with SE 0.980_e. But of course, the planets look a little different.

Of course you could easily adapt it for SE 0.980.
You just have to change in the planet script 'PeriodDays' into 'Period', and divide the numerical value by 365.24218985!

Sorry I meant .980e, I was using that exclusively until I bought .990.  I hope it can be used with both.  In relation to 0.990 will there be a process established to automatically upload your wonderful additions to the program, JD?

At some point I hope you can tell me/us how to use the console in .990.  I want to learn how to do the lat/long and fov thing you told me about for .980(e).  I also want to able to figure out how to shorten or remove the object descriptions!  And is the horizon leveling shortcut the same as it was for .980(e)?  Thanks!

The key commands have remained the same. (Essentially.)
Of course, the console / script commands are changed.
You can look here: http://spaceengine.org/manual/making-ad ... o-scripts/
That's admittedly not quite up to date.
