Omega Galaxy

This is a work in progress and I don't recommend this add on if your computer can't handle Cham's 1,000,000 stars add-on. This add-on basically is a galaxy that currently has over 1,000,000 stars, most of which are in a sphere that is 2,000 light years across. http://fedtrek.com/staff/omega13a/celes...

Re: Forum black-out ?

Same here. I was only able to view the forum by going to http://celestia.sourceforge.net/ first... Its like there's some kind of ant-hotlinking protection that's a tad too sensitive in place... :?

Re: 5 planets detected orbiting Tau Ceti

Why? There's a ~100 Earth-mass planet in our solar system with less surface gravity than Earth. Clearly the planet's mass can't be the only deciding factor in the surface gravity. Since when does Saturn have a surface? :wink: Technically, it does. If you go down deep enough, you'll find something s...

Re: Current project: Modified Stargen (a solar system genera

hmmm... It might be possible for me to add that though I'm going to need to make a list of letters and numbers that aren't used as arguments since most of them are currently used... I'm also thinking of added support for spectral types since the a star's spectral type appears to affect the albedo of...

Re: 5 planets detected orbiting Tau Ceti

In the article I read, the one in the habitable zone is the smallest yet detected in the habitable zone of a star.

Re: Current project: Modified Stargen (a solar system genera

I'm slowly getting a new version ready. This next version has three new types of planets: iron, carbon, and oil (basically the same as carbon but has liquids on its surface). I need to run a few more tests due to a bug that causes rocky planets to be way more dense than iron planets... :? MinGW? I j...

Re: Current project: Modified Stargen (a solar system genera

I was able sneak onto my dad's computer after he went to bed and installed cygwin and built the windows binaries. My dad is really sensitive about me using his computer. He's afraid I'll skrew it up. Truth is, he has skrewed up four computers, wrecked three calculators (all of which he borrowed from...

Re: Question about rotation periods

The rotation periods of stars in the source code are given in days from what I can tell. And yes, type F stars appear to rotate fast, at least according to who ever contributed the data to Celestia.

Current project: Modified Stargen (a solar system generator)

Basically what this is is a modified version of Stargen that was discussed in this topic: http://www.celestiaproject.net/forum/viewtopic.php?f=8&t=16807 The most important changes have to do with radii and densities of the planets/moons generated. All the solid worlds are now made out of some co...

LHS 2520

I was reading the headlines on NBCNews.com and came across this article: Superman's planet Krypton 'found' — with a little help For those who are to lazy to read the article, the star which Krypton supposedly orbited was chosen to LHS 2520. Being it is a real star that's not in Celestia's database, ...

Re: Current project: PHP/MySQL star generator

You download the source code and go through the code. The numbers I got are in src/celengine/star.cpp.

Re: Current project: PHP/MySQL star generator

I wrote something in PHP that does that. It uses some code from Celestia and stargen. Here it is: function makeStarTempTable() { global $cache; $cache_name = "star temps"; $temps = $cache->get($cache_name); if ($temps !== false OR _read('force', TYPE_BOOL, false)) { return unserialize($tem...

Re: Current project: PHP/MySQL star generator

A good little improvement would be to not use abrivations for the types of planets. For example what does MSI mean?

Re: Verona Planetary System (Fictional)

Not sure why Escalus is pink. I'd imagine a brown dwarf to be dark red or orange. Do you see it pink in your screen? Because I coloured it purple in mine. Maybe a difference in saturation settings. Also, I read somewhere that methane-rich brown dwarfs could have a purplish color. I admit I exagerat...

Re: Current project: PHP/MySQL star generator

Do L- and T-class stars come in giant? I do not know of any L and T class giants. And what's the mass range for Ls? What I was reading suggested to me that L dwarfs basically range in size from brown dwarfs (13 J) to the lower end of MVs. Is that at all correct? And I also understood (probably inco...
