A quintuple star system

[Sanduleak]

This is the general layout of the Rosphevron quintuple star system. I will update the thread and provide the ubox file as I'm able to sort out and freeze two types of information: the long term stability of the orbits and the textures (see this thread).

The system is made up of two close binaries, A-C and B-D, along with a significantly further E component:

E----------(AC)--(BD)

The whole system revolves around a barycenter located near massive star A, the two brightest stars being named Ethel (A) and Sampernor (B).


AC system

The A-C period is 8 years 3 months 3 weeks.

Star A: Ethel (center of coordinates), 26.6 sun
  Planet a: Orounisen (retrograde), 7.4 jupiter, period 1 year 5 months 5 days
     Moon I: Mack, 0.054 moon, period 17 hours 36 minutes
    Moon II: Faustus, 1.27 earth, period 35 hours 12 minutes
    Moon III: Shantycool, 0.28 earth, period 4 days 9 hours and 20 minutes
    Moon IV: Casimir, 0.019 moon, period 10 days 23 hours 50 minutes
    Moon V: Chardon (retrograde), 0.67 moon, period 38 days 14 hours

Star C: (prograde), 2.8 sun
  Planet a: Gnagax, 0.83 earth, period 116 days
    Moon I: Balines, 0.084 moon, period 7 hours 58 minutes
  Planet b: Imogen, 0.34 earth, period 291 days
    No moons
  Planet c: Pharanidon, 0.93 earth, period 1 year 4 month 1 week
    Moon I: Coromar, 0.47 moon, period 13 days 20 hours 40 minutes
    Moon II: Saandromar, 1.68 moon, period 32 days 10 hours 20 minutes, inhabitable


Coromar is in a 7:3 orbital resonance with Saandromar.
Faustus is in a 2:4 orbital resonance with Mack.
Shantycool is in a 1:3 orbital resonance with Faustus.
Casimir is in a 2:5 orbital resonance with Shantycool.



BD system

The B-D period is 4 years 6 months 3 weeks. The system is about 87 AUs from A-C's barycenter.

Star B: Sampernor, 7.5 sun
No planets

Star D: (prograde), 0.85 sun
No planets


E system

E orbits the barycenter of ABCD every 2755 years approximately.
Star E: (retrograde), 0.73 sun
  Planet a: Womwath, 2.21 earth, period 245 days
    Moon I: Addar (retrograde), 0.024 moon, period 49 days
  Planet b: Bomberos, 0.57 earth, period 59 years 6 weeks
    Moon I: Ghoul, 0.52 earth, period 22 hours and 30 minutes

Coolio...

Thanks  

Confirmed parameters are shown in green. Thinks to do are in red.

You should be one of Dan's helpers.  

The system is awesome. I love how B and D orbits in a high inclination.
By the way, they barycenter is 1/4 the way from A and C to B and D (includes E).

First picture shows a random earthlike planet orbiting E. Note that B and D transits.
Second picture is where the barycenter was located.

Thanks for the tip about the barycenter, I didnt notice and that will help me a lot

Your welcome. About barycenters (and binary orbits): http://universesandbox.com/forum/index.php/topic,1026.0.html

Can't wait for the textures.
The light system is like that because in the past, it was glitchy. It used to work in Beta 1, 2, and 3. But it got glitchy again....

[Sanduleak]

A focus on the Bomberos planetary system: the satellite, Ghoul, is so big that it produces strong wobbling in Bomberos' trajectory around star E.

Not unlike Pluto and Charon.

Coolness

[deoxy99]

*dies of amazement* Amazing, I think that is better than the textures themselves, but they are cool as well.

Cool System+Cool Planet Textures=Amazing

I posted a video showing the rotation of Mack (Orounisen moon I) here:

Enjoy!

You are better than me! I have to build it within the program, my XML's do not work at all although I used the right tags. The textures you made are too hard for me to make.

[atomic7732]

XML's work.

[deoxy99]

No matter how I put the tags together, it doesn't freaking work. XML has billions of cons, one is it doesn't work.

[atomic7732]

Do you level them?

<xml version blablablablah>
<System>
       <Body>
              <Object> Earth</Object>
        </Body>
</System>

or something like that?

Do you capitalize the "Object" and other tags?

[deoxy99]

I don't capitalize, I level them. It never works.

[Dan Dixon]

I don't capitalize, I level them. It never works.

If you're having trouble just post the XML in the help section and we'll help you figure out why it's not working.

[atomic7732]

Maybe you need the capitaliztion. 

[Sanduleak]

Yep the US XML parser is very reliable, I'm sure we'll be able to sort out your file.

Orounisen was a lonely giant, she could have been a star but was a little bit to small to ignite... If her plight makes you sad, you'll be happy to know that she is not alone anymore

400,000 km in size? About half of a red dwarf and size of a brown dwarf.

Orounisen's radius is about 140Mm, yeah that's a big baby. I thing if she would weight like 10 jupiters nuclear reactions could begin, but she's only 7.4

Also I spent a lot of time reshaping the star system, because I came to realize that it was too hot to support planets with atmosphere. And Saandromar would probably have evaporated under the previous conditions (combined heat from A+C). Now it stands right in the middle of Ros C habitable zone.

[Naru523]

Haha, true.
