Stellar Cartography: The KIC8462852 System

Assuming I got the Planetary periods right, this is what Tabbys Star System looks like:

  Planet            Period(days)      Dist(AU)     Temp (Kelvin, Celsius)     Planetary Size 
  Foundry               12                 0.11557             1199K,   925.85C             I                  
  Crematoria             22.5             0.17832               972K,   698.85C            II
  Inferno                    23                0.17573              965K,   691.85C              I                  
  Bonfire                    24.5             0.18599               945K,  671.85C              I
  Ember                      51                0.30322               740K,  466.15C             III                

So with an Albedo of Fresh Bitumin (0.02) it was cooler than Earth-like (0.3) Albedo. Hell is apparently cooler than Earth. The names seemed suitable. There is a larger trend in the data curve that is so slow in its transit of the star that it could mean a massive debris field stretched out from a planetary glob.

It might be nice out on the edge of the system clinging to an asteroid.

Update (5/9/2017): size of exoplanets
You can take the brightness dip and determine planet radius. so three size categories now added. Given the method I use here is visual, you can assume +/- 20% error.

 Category   radius (solars,       kilometres) 
       I           0.1059896221,    73,736.98     
      II           0.1171759361,    81,519.59
     III          0.158,                    109,920.6    
  Jupiter                                     69,570km  

So a bunch of 'bigger than Jupiter' planets orbiting very close to the Star.

Note (7/9/2017): Naturally Occuring Dyson Spheres
With Foundry at 1199K it should be noted that the most likely four elements of Hydrogen, Helium, Oxygen, and Carbon do interesting things at such temperatures. Graphite formation from Supercritical Carbon Dioxide dominates this temperature and pressure in the early system. Once the graphite layer formed it protected what was inside the graphite shell while carbon from external SCD continues to be deposited as oxygen and hydrogen separate off. Its possible for life to exist in the dark of this graphene dyson sphere made from heavier elements. Above that graphite the Oxygen and Hydrogen could form a Solid water or Oxygen lattice with Hydrogen Plasma in the lattice thanks to pressure and gravity.
