### JackDole's Universe

How to make a simple binary solar system.

1. Create a StarBarycenter:
// Example

StarBarycenter "MyTestStar"
{
RA      10 25 12.57
Dec     -27 37 12.87
Dist    171.53

Class   "G2 V"
}

BinTestBary.sc

Sometimes something like this appears:
Type            Blue hypergiant
Spectrum        O0 0

Therefore I recommend to use the spectral class of the main star as 'Class'.
(But that only happens when you make a 'StarBarycenter' without a 'Star'.)

2. Create two Stars.
// Example

Star "MyTestStar A"
{
ParentBody  "MyTestStar"
Class       "G2 V"

MassSol     1

Orbit
{
SemiMajorAxis   0.333333333333333
Period          0.816496580927726
Eccentricity    0.0
Inclination     0.0
AscendingNode   0.0
ArgOfPericenter 0.0
MeanAnomaly     0.0
}
}

Star "MyTestStar B"
{
ParentBody  "MyTestStar"
Class       "K2 V"

MassSol     0.5

Orbit
{
SemiMajorAxis   0.666666666666667
Period          0.816496580927726
Eccentricity    0.0
Inclination     0.0
AscendingNode   0.0
ArgOfPericenter 180.0
MeanAnomaly     0.0
}
}

BinTestSys.sc

Eccentricity, Inclination; AscendingNode and MeanAnomaly must be the same for both stars. (I set all values to 0)
ArgOfPericenter must differ by 180 degrees.

SemiMajorAxis and Period must be calculated.

SemiMajorAxis is calculated using this formula:
SemiMajorAxis = Distance * MassA / (MassA + MassB)

and
SemiMajorAxis = Distance * MassB / (MassA + MassB)

Distance is the distance between the two stars in astronomical units (Au)
MassA is the mass of star A in solar masses and MassB is the mass of star B in solar masses.
(The second SemiMajoAxis can also be calculated by subtracting the first SemiMajorAxis from the distance.)

The smaller value of SemiMajorAxis belongs to the more massive star!

Period is calculated as follows:
Period = sqrt(DistanceAu^3 / (MassSolA + MassSolB))

That's it.

JackDole, I would like to say that you do us all an enormous service by designing these mods. There is obviously a lot of passion (and one or more sleepless nights!) put in these addons, and its my hope that they will be permanent features to the program. I think I speak for everyone when I say that the SE universe is not the same without JackDole's Universe!

A moon with a moon ...

(This .pak file belongs in the folder 'addons'.)
SereLleuLeud.pak

This addon only works with SE 0.980_e !
(And with the current version of SE 0.990.)

If you also want a moon for the moon of the moon, put this script in 'addons\catalogs\planets'.
Saor.sc

The sun of the system is called 'Sere Lleu Lleud'. The planet is called 'Clydwr' or 'Sere IV'. The moon is called 'Lleud / Sere IV.1'. The moon of the moon is called 'Lleu'.
(And the moon of the moon of the moon is called 'Soar'.)

Some versions of my Matrioshka Brain.

An accident.

I seem to be encountering a small problem with this. At certain angles the moons unrender/derender.

That's a known bug. Possibly caused by the unusual hierarchy of the objects.
But maybe the bug is already fixed in the current, non-public beta version of SE. At least I can not reproduce it till yet.

Tri Star

TriStar.pak

The planet is called Canlan.
For the background stars and the nebula you need this addon: JDVClusterNebulae.pak
