Re: [nbos] [AS] Binary Star Systems

When modelling multiple systems, one needs to be careful about planets
passing between close doubles (etc.) proto-planetary materials could
well have problems coagulating with such gravitational stresses.
MegaTraveller has a neat system for determining what orbits would not
contain planets under such circumstances. I don't know how accurate it
might be (does anyone?) but it seems reasonable to me.

Also, to get some ideas about the effects on habitable worlds orbiting
such systems, Brian Aldis' "Heliconia" trilogy is invaluable and a good
read to boot.

Cheers,

Mike

Thats something I'd like to do, but havent gotten a grip on the physics
of
it yet. A binary star system isnt a problem to model... but through in
a
third star and all bets are off :-)

I _was_ working on AU being an option in the system data fields setup as

part of the next minor update, but for some reason ended up not adding
in. The specific reason escapes me right now. But it is on my to-do
list
as quite a few people have asked for that.
