Current project: PHP/MySQL star generator

[omega13a]

I noticed in the output of http://www.tarazedi.com/files/backup%20 ... Sept10.php, some of the brown dwarfs are too massive to be brown dwarfs. The largest a brown dwarf can be is slightly smaller than Wolf 359 (about 0.08 solar masses). Also it don't seem to generate any class T brown dwarfs. Only class Ls.

... If anyone can show me some good numbers on spectral class and luminosity class distributions in clusters of age X, I would love to implement that

Perhaps this may help you:

Juast an example, with and without all those blu external supergiants (that appear even if Cluster Blue Loops are set to "0"), and eliminating the cube corners to give a more "spheric" shape to the cluster.
I made a lot of photoshopping to show it (a long and annoying job...).
And, Mneme, a pray: can you find another system for naming the obtained stars?
Names like this should be forbidden by law:

For Quatran that's not a hard name at all but I should drop a syllable from the possible range I guess. LOL Levetzi is easier.

The age loops skew toward giants; if you don't set that you should see few to no supergiants.

I know the very basics of cluster evolution, that a young cluster has more Bs and older clusters more red giants etc. but I don't know how to translate that into percentages. The age skew just increases the number of giants. I haven't seen any sources for the number of Bs, As, etc. for giants as I found for main sequence stars, so the distribution is just logarithmic.

Do L- and T-class stars come in giant? If not, I should probably edit those because the larger L-class stars I generate seem to be insane huge, like 100AU+. 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 incorrectly?) that a T-class is just a cooler version of an L-class and fall in the same mass range?

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 incorrectly?) that a T-class is just a cooler version of an L-class and fall in the same mass range?

That's correct from what I understand. L, T, and Y classes are all for 'failed' stars aka brown dwarfs. According to wikipedia, they have a mass between 13 and 80 Jupiters. Also, I would like to point out that Celestia doesn't support Y class brown dwarfs because they are a very recent discovery and there isn't a well defined spectral sequence for them yet.

Okay, things seem to be working alright.

http://www.tarazedi.com/files/stargenerator.php is the star generator current version. It produces stars and planets, though not yet moons. Be aware that multiple users hitting it at the same time may cause undesired results. Also, be aware that I will continue working on it and downtime should not be surprising.

http://f.tarazedi.com/viewtopic.php?f=7&t=28 has the textures pack and version 0.9 of the program.

Enjoy.

I'm working on v3, transferring and converting the code to the new format. Systems and stars are done. The program runs much more smoothly and loads the currently-generating system in an iframe, refreshing with each system rather than running a multitude of separate loops as the previous version did. The sidebar refreshes every ten seconds, showing current progress, tallies, and records (e.g. most massive system). Once I have the code converted I'm going to throw some images up so you can actually see a graphic representation of the system being worked on as it is generated rather than just data tables.

[Mneme]

http://w.tarazedi.com/image1100

Progress: graphics for star and planet types, scaled to radius (or square roots thereof for stars). Moons are next, then the various types of output page (Celestia, tables, and web formats e.g. HTML, BBCode, and Tikiwiki). After that I will improve the cosmetics, including changing the planet images to match subtypes rather than just the overall type (e.g. Ice Cratered, Ice Resurfaced rather than just Ice).

Still undecided on asteroids though.

[Mneme]

Alright, all I should have left is the alternate outputs (tables, HTML, BBCode, H-R diagrams, etc.); the Celestia output works fine. The appropriate clouds paste right over top of the planets and the graphics are a lot more varied. Also, I should probably add a "suppress planets" option eh...



Feel free to play with it. I'll be providing the source and web crap for this soon.

www dot tarazedi dot com slash starmaker

[Mneme]

http://www.tarazedi.com/starmaker/tableoutput.php generates an H-R diagram and a planet density/class/temperature chart as well as listing data for each system and planet. There will be additional tables at the bottom for moons and rogue planets when I get that far. The HTML output page will create the necessary HTML to generate a page like this for use on websites, etc.

[omega13a]

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

[Mneme]

Non-gas-giants: Ice, Ice-Carbon, Ice-Silicon, Carbon, Silicon, Metal-Carbon, Metal-Silicon, Metal, Remnant, Rogue.
Gas giants: Methane-Cloud, Ammonia-Cloud, Water-Cloud, Clarified, Alkali-Metal-Cloud, Silicate-Cloud, Vaporized.

Added a number of additional planet combinations. A few highlights I've run across in my travels:

You should use abrivations for the planet and moon classes without some key to say what the abrivations mean. All the types of out put should have something like that.
