There should (for Rule of Cool reasons rather than strict physics) be a steady stream of plasma being siphoned from one to the other. When beings look up into the sky they see two blazing orbs connected by a thin string in the middle - like chained cannonballs on fire. :B
Well, since the stars are so close together, it's entirely possible for them to transfer mass from one to another. It certainly would look cool.
But back on-topic. What's the closest the two moons ever come together?
Not close enough to knock each other out of orbit. They are quite far apart, one has an SMA of over 400K km, the other of over 100K. One is also less massive. That should be pretty stable... I think.
Yay, volcanic activity, caused a rise in atmosphere pressure and released a lot of water vapor into the atmosphere. Another 500 mil. years passed and the planet cooled down. The water condensed and formed oceans. Most of the CO2 bound to the water. No oxygen though. We all know how oxygen is made... Don't we...? Also, no life... Yet.
i blow hard against the surface of the world, and fill the sky with air (comprised of 30.28% oxygen, 65.2% nitrogen, 1.7% argon, 0.02% carbon dioxide, and 2.4% other elements)
there shall be breath
i declare it to be so
Sorry, but I agree with 10ebbor10. Let's do stuff as we believe it actually happened.
Around 300.000 km.
Also, not really falling into each other, but one of the stars is going to siphon matter from the other. Iy won't be entirely stable/
Yeah... But do we
want stuff to be stable...?

Now, time to do stuff! By the way, about 1 bil. years passed since the formation of the system. Also, we are halfway through the bigger star's lifetime. Don't worry though, the will slow down now, as we'll be focusing mostly on the evolution of life, I believe. Now, let's do some other stuff!
