Habitable zone addon

[Tuefish]

I had an interesting Idea today; to make a ring around the sun, representing the Circumstellar Habitable Zone, or CHZ, I already have the texture, so all I need is information on how to set a ring around the sun at the correct distance. any help would be greatly appreciated.

The HZ is hard to define. GJ581d isn't in the HZ, but it could be habitable if it's atmospheric greenhouse gas is high enough. Also, HZ for temperature? Or for UV amounts?

It my not be the most accurate, but try this http://en.wikipedia.org/wiki/Habitable_zone
This only assumes liquid water on planets with simple atmospheres. However with the correct atmospheric composition, Venus and Mars can be habitat, though outside the HZ

[Tuefish]

I read that Venus lies just shy of the habitable zone, and that mars lies just barely inside it, so I set the ring accordingly.

Tuefish,

this addon is interesting. Can you make it available ?

Hmmm... does seem like an interesting addon Tuefish, although im my spare time im working on exosolar planets around other stars, making their own textures and atmospheres based on what we know and theroretical science, and it would be a real help to have an addon that could be applyed to any star, calculating the size and distance of any stars habatable zone, sounds a bit farfetched and complicated, but would such an addon be possible?

[Tuefish]

Cham: I've just finished making the addon stand-alone, and will try to make it available via the motherload.

Cosmo: keeping in mind that the the study of habitable zones around extrasolar stars is, for the most part guesswork. the best I could do is make an addon based on available information, but extrasolar habitable zones do hold an interest for me.

Cool, if i knew how to make the addon and make the code for it e.t.c. i would have a go my self, unfortunatly all i can really do is mess with textures, atmospheres, stars, planets and moons.

If exososlar habitable zones interest you then you may find these handy:

http://www.extrasolar.net/ is an awsome site with detailed info bout the exosolar planets, wot they would look like and their orbits and where their habitable zones are!

http://en.wikipedia.org/wiki/Habitable_zone may also help. It has the 'habitable zone equation' where as long as you have the luminosity of the host star and the luminosity of our sun (which would be 1) then you can work our how far away the habital zone is from the star. Dont know how you would work out how thick it is though!

[Tuefish]

So, the motherload is taking a while to include the addon, so here is the code I use:

Code: Select all

"CHZ " "Sol"
{
Mesh "th_placeholder.3ds"
Radius 550000
Oblateness 0.00

EllipticalOrbit
{
Period 1E10
SemiMajorAxis 1e-10
Inclination 0.00
}

# RotationPeriod : the actual rotation rate varies with latitude L as: ( 14.37 - 2.33 sin2 L - 1.56 sin4 L ) deg/day
RotationPeriod 609.6 # 601.25h @0 deg or 609.6h @16 deg lat
Obliquity 7.25
EquatorAscendingNode 75.62

Rings {
      Inner  110000000
      Outer  230000000
      Texture "CHZ.png"
   }

RotationPeriod 0.109
Obliquity 45
}

just copy and paste it into a blank ssc file and create the necessary folders.

and Here is the texture. Just copy the image into the correct folder.
Feel free to change this addon any way you want to.

Very interesting add-on, Tuefish. It could be improved, in my humble opinion, with the reference to the temperature and UV's spread, as Hungry4info call for, by some 3d texts and/or color bends.
