Brown-Dwarf planets question

[Daynarr]

Thanks a lot guys . It really is helpful for what I am doing (and I found out I was mistaken about their size as well ).

I don't know how many of you remember my first quadrant mod with additional systems (had 1-12 planets in them) and new nebula graphics. Well, I'm working on a new Version of it - much bigger and complete in both graphics and text department. Its still going to focus on quadrants alone so it will be completely compatible with nearly all non-quadrant mods out there. One of the features I wanted to add are Brown Dwarves but I needed info to know what composition type and what size they are. As far as size goes, I have found a nice graph that represents size 2 of the found Brown Dwarfs, Red Dwarf star, our Sun and a Jupiter. Brown Dwarves come in large variety in both composition, size and atmosphere types, so in SE4 I will allow them to be of any atmosphere type have a population capacity somewhere in between Huge Planets and Ring Worlds, a little more facility capacity then huge planets (not close to Ring Worlds, about 30 will do) and make them both Rock and Gas Giant composition type. However, I have a dilemma about making them Ice planets as well. Since these not-to-be-stars are having some self-illumination (and certainly increased heat) would it be possible for this "planets" (actually I believe they are classified as planets, or at least they were) to have ice surface? If that were possible it would make balancing them easier.
