[QUOTE="Desdichado, post: 2337790, member: 2205"] Well, a big part of the fun of having the planet be a satellite of a gas giant or brown dwarf is so that it can have a big glowing and striated feature in the sky that looks really cool. The only problem is, to have a reasonable chance at habitability you need to be a bit farthur out, which somewhat minimizes the impact of that. Personally, I think that's something that can in good conscious be modified for dramatic effect, but I'd never do that without knowing the implications, myself. ;) As for the heat, no, that's not necessarily a problem. If anything, it means that you can move the entire system farthur away from the star, because if doesn't need to get all its heat from the sun anymore. Being tidally locked doesn't mean that there's a light and a dark side; it means that the brown dwarf will always be in the same position in the sky; it will never rise and set. But the sun still would, and presumably that's what's causing your day and night. Of course, that's where I start losing control of the mathematics of the model, when I have to try and calculate all the effects of rotation around the brown dwarf, the brown dwarf's rotation around the sun, and what all that does to seasons, days, years, etc. Also, if you are tidally locked and the brown dwarf is a significant source of heat, then you've got odd hemispherically dominated weather patterns; one hemisphere is significantly hotter than the other, meaning that prevailing winds far beyond anything in our own world will race around the surface of your world. As for the tangled up magnetic fields; that's just a metaphor; the magnetic fields aren't actually strands that can get tangled. It's generally believed, though, that the disruption to the magnetic fields means they aren't effective at shielding from solar radiation. So, it's all doable. I get a bit lost in the model when I try to calculate the effects of it, though. But if can be done, and you could probably handwave away most of the problems I've spelled out and few people would quibble. [/QUOTE]
