Unexpected Guest Post - Sean Meaney

This arrived in my inbox from Sean Meany, unprompted, this is the first message that Sean ever sent me.

"First off a text of a blog post I did regarding KIC8462852 for background:

  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.

Now to suggestions for Deep Carbon Observatory 2:

So consider if you will a naturally occuring graphite sphere close to the Sun. That which is within the sphere has cooled providing an environment where deep pressure life might spawn in darkness beneath a shell of carbon. But the pressure drops off as the contents of the sphere cool and contract. Shell fragments are hurled out into the solar system because of collisions in the early system, and due to imperfections in the shell there is a small pocket sphere or bubble where the trapped elements cool and life might evolve in the dyson sphere. Life that might have no eyes, but might sense your electromagnetic brain waves like a telepath. That shell fragment drops to earth becoming a part of the planet. Someone looking for diamonds might find the graphite layer possibly coated in an Oxygen Opal (solid oxygen crystals) and come under its sway. Evil air elementals mining Solid Oxygen beneath the earth.

  1. I for one did not expect him to post here today.

  2. Oh, this is quite interesting. Actulally, I found your blog on google search. I will tell my friend about your blog later.
    Heavy machinery import Pakistan

  3. Crazy shit like this jump starts my imagination and then when I continue the story in my own mind it becomes lackluster and boreingly normal.
