(I am of two minds about posting this here or in the main satrophytsics forum, but I think it's probably better to go here.)
So, I have a tide-locked planet at approximately 104AU out around a clone of R Coronae Borealis, with has a carefully designed , bright shiny silvery moon (small and close by) which is a relatively recent (few billion years) capture; with a rotational speed of three days on it's own axis and six days around the planet.
I have two, proabbly related problems that have come up, the former due to the latter.
a) Given that these are both well within the (theorised) carbon dust cloud resulting from the star, why are they both not completely black with picked up carbon?
b) Given that for what little I've been able to glean from the subject, R Coronae Borealis will have a stronger stellar wind than Sol (which will presumably not tail off at that distance), albiet one that will fluctuate more, so how does the planet maintain its atmopshere?
It is clear that there needs to be A Field of some description to prevent these problems.
The magnetosphere is the most obvious one, since if it was strong enough, it would both counteract the stellar wind and - I presume, correct me if I'm wrong - be enough to deflect the carbon dust around the planet (in the majority of the time). The problem is... How do you generate a magnetosphere with no significant planetary rotation to speak of?
I had thought about the liquid iorn (et al) cores of the planet and moon interacting and forming some sort of dynamo effect but that has a few problems:
1) I'm not quite sure Magnets Work That Way
2) If it does work that way, it seems to be a magnetic interaction btween a planet and a moon (especially one that's going to be spiralling IN, not out) is more likely to end up pulling the moon smack into the planet.
3) If it does work that way and it doesn't cause the moon to smash into the planet - it still begs the question of how the planet's atmosphere would have formed before the moon was captured.I'm getting the impression - bearing in mind I've only got wiki articles tro work from - that its sort of possible to get a magnetosphere in other ways than just the dynamo effect (or at least without such a significant imput of rotational energy).
I am floundering a bit in how to proceed further here: I would greatly appreciate any suggestions - magnetopshere related or anything else which might do the job (or places on the internet I might be able to at least make a spirited attempt to hazard and answer). I'd have to have to, at this stage, resort to essentially "it's magic, shut up..."
It's obviously a fairly major issue (can't quite understand how it's slipped past until now), which needs resolving before I can go any further: especially because it may well have an influence on the flora and fauna of the planet. (If it has to have has a crazy-strong magnetic field, for example, magnetosense might be a very common sense in most creatures.)
