Re: Plaintive Cry

A quick resurrection of this old thread with a few questions:

If the Gas Giant's orbit was inclined to the solar equator, would its exposure to the maximum solar wind strength be reduced enough to have an effect on its radiation belts?

Are there any theories on the rate of decay of a Gas Giant's magnetic field? Is it plausible for one to lose enough strength over a reasonable time (i.e. well before the central star enters the twilight years of its life)?

On a different note, mega-earth or gas dwarf exoplanets could be substituted for gas giants for traditional Traveller inhabitable gas giant moon situations.

As I understand it, the radiation belts are pretty
much entirely dependent on the solar wind. If the jovian is
closer to the star then there will be a lot more radiation
because the wind will be stronger (due to the inverse square
law). Cool stars will have habitable zones that are much
closer than warmer stars, so if anything the problem could
be even worse there. 

If
the jovian had a weaker/smaller magnetic field then that
would offset the problem somewhat.
