Solar system

[flet]

Is it dynamically possible to have more than one asteroid belt in orbit around a star? If so, would the number of belts depend on the mass of the star?

Would a B star for instance, on average, have more belts than an A star?

You could say that our system has two belts. The Mars \ Jupiter and the Kuipers a lot further out. I think it is more dependent on the creative dynamics of how the particular system was formed but until we get out there and look at other systems it would be hard to put rules on anything.
We keep being surprised by how many of our 'rules' are not complied with by other systems already. Planets and multiple suns eg.

I think its very possible, I don't think asteroid/debris belts are a final "state" more a transitional state. Think beyond the here & now our solar system is still evolving and changing over a long timescale, its not settled into equilibrium and no reason to think ours is "the rule" anyway. It's just a single good data point to study.
