GregroxMun: I guess you did not know about that
<GregroxMun>
I didn't.
<GregroxMun>
This is great news I think.
TonyC1 has quit [Ping timeout: 204 seconds]
<Sigma88>
yup
<GregroxMun>
Using ModuleManager I think I can make a Star Generator that would be able to create stars based purely upon their mass.
<GregroxMun>
It would only work for the main sequence, and you'd still have to manually put the colors for the spectral type in
<GregroxMun>
but the mass/radius/luminosity etc would be defined by the config.
<Sigma88>
why can't you make the color automatic as well?
<GregroxMun>
Because I don't know how.
<GregroxMun>
I suspect it's possible to go as far as have temperature be calculated into RGB color Kelvin by ModuleManager.
<GregroxMun>
But I don't know how to do that.
<Sigma88>
if you can calculate the color you want then it's possible to automatize it with MM
<Sigma88>
if you have the math but are not sure how to translate that into mm syntax just ping me
<GregroxMun>
Each star needs two temperatures to be calculated: Sunspot Color and Star Color. Sunspots are cooler and thus would be towards the redder end. Sunspot color would also be 1/4 the brightness of Star Color.
<GregroxMun>
Oh crap, the calculator I've been using only goes up to 15000K, but I need 15200K and 36000K
<GregroxMun>
I'll have to wing it for the O9V star, but 15000K is probably close enough for my purposes.
<GregroxMun>
for the B5V star
<Sigma88>
it requires the LOG
<Sigma88>
which can't be done via MM
<GregroxMun>
blast.
<Sigma88>
calculator?
<GregroxMun>
Wait, there are polynomials that can approximate logs.
<Sigma88>
I don't even understand where the tool is
<GregroxMun>
something broke then
<Sigma88>
ah ok
<Sigma88>
I didn't see the slider
<GregroxMun>
I have a "cheat sheet" of handwritten equations and formulas that regard stars for the sake of worldbuilding and starbuilding. But it's really ugly and in a broken sketchbook that I have to take out of my desk every time I want to look at it. I am considering just making one really nice big cheat sheet and having it printed nice and large to put on
<GregroxMun>
my wall behind my screens.
<GregroxMun>
Probably would have planetbuilding equations and other formulaic miscellany too.
<Sigma88>
you should take the Temperature from the star
<Sigma88>
where do you define the temperature of a star?
<GregroxMun>
atmosphere I assume.
<Sigma88>
ok
<Sigma88>
fixed
<Sigma88>
reload now

http://i.imgur.com/boQwLDF.png orbital mechanics around a B5V star. 19 years to Eve, but on the bright side it's under a km/s to get there.
<GregroxMun>
Should you want to dive into the sun, it will cost you only 2.5 km/s or so.
<Sigma88>
let me know if MM throws any errors with that
<GregroxMun>
and what a sundive it will be
<GregroxMun>
ok.
<GregroxMun>
Oh shoot here's a roadblock: no way of chosing the right color for coronas
<Qboid>
Sigma88: Seems that Wolfram is unable to understand that.
<GregroxMun>
roughly
<GregroxMun>
it's 0.1 Msol
<GregroxMun>
^the above pic I mean
<GregroxMun>
I'm quite happy with the way it turned out for low mass stars. They're really sense so I wouldn't expect limb darkening to be very obvious.
<GregroxMun>
s/sense/dense
<Qboid>
GregroxMun meant to say: I'm quite happy with the way it turned out for low mass stars. They're really dense so I wouldn't expect limb darkening to be very obvious.
<Sigma88>
GregroxMun: you make no dense
<GregroxMun>
That's "American" quite by the way, as in "really"
<GregroxMun>
America and England have different ideas of what "quite" means for some reason. It's the opposite between them.
<Sigma88>
quite interesting topic
<GregroxMun>
I'm curious if europeans learn english that's closer to British or American.
<Sigma88>
in italy they teach british in schools
<Sigma88>
but I ended up learning american better because of tv series and movies
<Sigma88>
and because I hate studying
<GregroxMun>
That makes sense.
<GregroxMun>
lol
<Sigma88>
ironically
<GregroxMun>
Something annoying is that half of the spectral types on the main sequence have nice tables in them and half of them don't on wikipedia.
<GregroxMun>
Like G-type main sequence stars have a table with lots of nice info, but K and F don't.
<KillAshley|SEMI>
thought so, but cbf looking up github lol
<Sigma88>
KillAshley|SEMI: I don't think it's much reliable
<KillAshley|SEMI>
its just needs to be general, i only use it for kerbin in NH
<Sigma88>
my suggestion is to use hyperedit to move a planet to orbit the body at the altitude you want
<Sigma88>
iirc it calculates the SOI, it doesn't use the one you set manually
<Sigma88>
if you set one
<KillAshley|SEMI>
it does update to manual SOI's
<KillAshley|SEMI>
:P
<Sigma88>
ok
<Sigma88>
I usually just move the mun to the altitude I need
<Sigma88>
:D
<KillAshley|SEMI>
lol
<Sigma88>
KillAshley|SEMI: science defs are making me go crazy
<Sigma88>
Z_Z
<KillAshley|SEMI>
lol
<KillAshley|SEMI>
whats up
<Sigma88>
nothing, I have to set up all the science for SASS
<Sigma88>
30 bodies
<KillAshley|SEMI>
lol
<KillAshley|SEMI>
welcome to my world
<Sigma88>
I've checked all the definitions themselves
<Sigma88>
now I need to fix the biome names, colors and maps
<KillAshley|SEMI>
:P good luck
<Sigma88>
all without manually editing stuff :|
<KillAshley|SEMI>
ok so my 3 main packs are now done. just need a kopernicus update before i can release lol
<Gregrox|AWAY>
o/
Gregrox|AWAY is now known as GregroxMun
<KillAshley|SEMI>
hey GregroxMun
<KillAshley|SEMI>
not sure erther i want to update K+ again
<GregroxMun>
I could do Kerbol Plus Rekerjiggered. Full circle. XD
<KillAshley|SEMI>
lol that mod got passed around
<KillAshley|SEMI>
me problem is;
<KillAshley|SEMI>
if i update it, i would want to completely bring it up to the standard in my NH, UL & KASE packs
<KillAshley|SEMI>
and that would take a lot of work
* KillAshley|SEMI
shudders
<GregroxMun>
And all for work that isn't really "yours" in that they aren't your ideas.
<KillAshley|SEMI>
well most are actually mine lol
<KillAshley|SEMI>
thats why i stole the mod to begin with
<GregroxMun>
Oh wow.
<Sigma88>

<GregroxMun>
o/
<KillAshley|SEMI>
dont you remember all that drama
<GregroxMun>
yes I do
<GregroxMun>
But I thought at least the plans and system layout was his
<GregroxMun>
ideas for what things looked like
<GregroxMun>
etc
<GregroxMun>
I'm trying to decide how I want to implement vertical drift along the Main Sequence.
<GregroxMun>
(Essentially, relating to the fact that both Sol and a Cen A are G2V, but a Cen A is something like 10% larger and twice as luminous.
<GregroxMun>
)
<GregroxMun>
!wa luminosity of Alpha Centauri A / luminosity of the Sun
<Qboid>
GregroxMun: Rigel Kentaurus A | luminosity/Sun | luminosity: 1
<GregroxMun>
!wa radius of Alpha Centauri A / sun radius
<GregroxMun>
that's not true.
<Qboid>
GregroxMun: Rigel Kentaurus A | average radius/Sun | average radius: 1
<GregroxMun>
!wa (Rigel Kentaurus A luminosity)/(Sun luminosity)
<Qboid>
GregroxMun: Rigel Kentaurus A | luminosity/Sun | luminosity: 1
<GregroxMun>
maybe I'm wrong
<GregroxMun>
1.5 Solar Luminosities.
<GregroxMun>
1.227 Solar Radii
<Sigma88>
GregroxMun: do you know the name of the kerbal texture in the astronaut complex?

<GregroxMun>
One of the problems with vertical drift along the main sequence is there's no nice equations for it.
<GregroxMun>
Not that I know of.
<GregroxMun>
Maybe I'll just make it a horizontal drift. This would act the same as vertical drift but i would have only one variable to worry about: temperature. You could consider a Cen A to be a star that is the same horizontally as the Sun but higher vertically, or you could consider it the same vertically as some F9V or G0V star but different horizontally.
<GregroxMun>
drift implies change so its maybe a misnomer
<GregroxMun>
anyway the main sequence isn't just a wiggly line. It's a strip.
<GregroxMun>
It has width
<GregroxMun>
stars can be the same mass and radius as one star, but hotter.
<GregroxMun>
Sigma88: what do you think about replacing GN star colors with the more realistic ones generated by the config?
<GregroxMun>
You don't even have to worry about things breaking due to automation, just steal values from the MM cache once it's generated once.
<Sigma88>
if it looks good I'm ok with it
<Sigma88>
GregroxMun: where's the fun in that?
<GregroxMun>
You said you didn't like having too much automation because things might break, right?
<GregroxMun>
If you're fine with it then fine.
<Sigma88>
depends, if the automation is solid then I'm all for it :D
<GregroxMun>
AFAICT it's fine
<Sigma88>
what was I talking about?
<Sigma88>
I don't remember
<GregroxMun>
I'm trying to remember.
<GregroxMun>
You know how Sigma Dimensions scales atmospheric pressure if you want it to?
<GregroxMun>
Is it possible to get it to do so for temperatureCurve?
<Sigma88>
yes
<GregroxMun>
And then implement it into the star generator config.
<Sigma88>
yes
<Sigma88>
temperature curves for stars don't really do that much
<Sigma88>
they are pointless
<GregroxMun>
They make you go boom at the right temperature don't they?
<Sigma88>
when you get close enough to be affected by the temperature curve, you would be burn by the luminosity anyways
<GregroxMun>
!wa Rigel Kentaurus A mass
<Qboid>
GregroxMun: Rigel Kentaurus A | mass: 2×10^30 kg (kilograms)
<Sigma88>
nah, you can burn way before getting to the atmosphere
<Sigma88>
the atmosphere is there just to give the "drag effect"
<GregroxMun>
!wa (2e30 kg) / (sun mass in kg)
<Qboid>
GregroxMun: (2×10^30 kg (kilograms))/(convert Sun | mass to kilograms): 1.005816
<GregroxMun>
Huh.
<Sigma88>
and because since stars do not have a PQS, they need to have an atmosphere to make the ship autoexplode once it goes 250 meters inside the scaledspace
<GregroxMun>
ok
<Sigma88>
I can't understand how TR recolors the heads >_>
<Sigma88>
oh wait
<Sigma88>
I think I know what's going on
<Sigma88>
TR doesn't read the version edited with MM
<Sigma88>
reads the actual cfg file
<Sigma88>
if that's true it's a huge facepalm
<GregroxMun>
!wa Rigel Kentaurus B mass
<Qboid>
GregroxMun: Rigel Kentaurus B | mass: 1.5×10^30 kg (kilograms)
<GregroxMun>
!wa 1.5e30 kg / sun mass
<Qboid>
GregroxMun: 1.5×10^30 kg/M_☉ (kilograms per solar mass): 0.7544 kg/kg (kilograms per kilogram), 0.7544, 75.44%
<GregroxMun>
I'm guessing that 0.7544 is correct even though wa misinterpreted me a tad bit
<GregroxMun>
just to be sure...
<GregroxMun>
!wa (1.5e30 kg)/(sun mass in kg)
<Qboid>

the first number is distance, but where 0 is really far away and 1 is really close. the second is brightness. The other two are calculus bits iirc that you can just put as 0 each. (you do have to have all four numbers though in each key)
