Chen, these references are new to me, but the argumentation looks sane from a scientific view. It seems even if Sirius A has no true deep convection zone, there is at least a very thin portion at the boundary "star interior vs. atmosphere" which is in motion. The author you cited tells about "photos...

Chen, as far as I know Sirius A probably will not have a granulated surface like the sun. Main sequence stars like Sirius A and the Sun develop an outer convection zone only in the low-mass branch (say, up to 1.5 solar mass units). An OCZ is turbulent "boiling" gas which transports the heat energy o...

Please accept my apologies. I just realized......

... never mind.

Selden, I made some furher test. First, the effect also is visible when turning Beta Lyrae around by mouse movements. It then looks if not the texture of the farther star disappears but something else appears in front of it. When I set "Sheliak B" to a wider orbit SemiMajorAxis 0.24 for example, the...

Selden, I just performed some tests. First I set back my system to one monitor to exclude it was a twinview problem. One star texture still disappears, and it happens even if the stars fill the entire window and in only 1000x time. For testing, I started nothing but X and the twm window manager and ...

Buggs, this addon will be a real killer.... :) A note: I took my "quick & dirty" Beta Lyrae (which was just a test of the new .stc features) inspiration from a painting which was printed in an old popular science book. Loved that painting when I was child. Science has proceeded a bit meanwhile.....

Selden, what I see is that the texture disappears for the star which is more far away from the observer. This happens if the system rotates (timerate 1000000x or so). There also seems to be something like a radius change (very little but noticable if close enough). System Config: I 've Debian Linux ...

Hi folks, have been lost in the "outer space" of business for a long time... just a few days before I finally found some time to install the long-ago downloaded 1.4.1. A LOT OF THANKS TO ALL!!! @Fridger & Toti: Galaxies look very amazing now. I guess I will set up at least part of the Virgo Supe...

Thanks for the tip about -
I now use qjoypad 3 and it works quite well!

Chen, in fact I did what you suggest - as far as it was possible. The Apollo 10 LM crew had to examine the Apollo 11 landing site, so the perilune of the LM descent orbit must have been the same for both: 15 km above the Apollo 11 landing site. This gave me information of the moon orbit of "Snoopy",...

Thanks a lot for that hint, I will checkout it immediately!

Hi folks, just uploaded an Apollo 10 addon. Apollo 10 was a quite interesting mission, it left a lot of flight hardware still in existence... Lunar Module 4 "Snoopy" was sent to solar orbit after completion of its mission. Couldn't find orbit data anywhere, so I calculated an approximate orbit from ...

Heh, I had a screamin' Commodore 64, yeah baby...

HA!!! Buggs was a "bread box" boy....

Hi all here, I watched out for some time the discussion about Chris' disapperance and how the development of Celestia can go on in the mean time. And I want to give some very personal thoughts here, about Celestia, what's its meaning for me. Nothing technical but philosophical. Watching out for the ...

Jestr, I love that hires map, especially if including your Stonehenge addon. I use it as "Stonehenge Starflight Base", and it's really fine to start into space and to see the fields of South England slowly disappear. I live in Germany, but a couple of years ago I visited Stonehenge. :wink: ~Diane.

Maybe a silly question, I don't peek that often into the forum... On which 1.4.0pre version FT is based? I would like to know *before* I slurp 15 M or so through a 56k modem line. I have a special interest in the binary star orbit stuff. @toti, Fridger: Good work, keep it alive. Celestia MUST NOT di...

Just searched the forum and found some old posts about joystick support for Linux. The reply in all cases was an unisono "Not Yet". However, I have a standard /dev/js0 jovstick which works well with some test tools like jstest under Linux. Nevertheless Celestia 1.3.2 doesn't acknowledge it in any wa...

Selden, thanks for the hint about Anim8tor, I will try about it. Guess it nevertheless will take a lot of time until I'm practiced enough to create simple 3D objects. A simpler way for me could be if there were kind of "human readable" 3D data file format, maybe in the form of a long list of triangl...

Maybe you can upload it to your homepage? I'm curious to see it. Moreover, I would have more fun in calculating the trajectory if I need not to take a grey ball as model as long as yours is not available. :) BTW, seems you're more experienced in work with 3D programs than me. (I have blender but to ...

As far as I see, Orbiter does some particle trace methods to have exhaust trails or at least a reentry wake. (Browsed the site for a better model of the S-IVB stage to have a possible improvement of the J002E3 addon) I remember from my work in aerospace research that particle trace methods aren't th...
