re: Mr. Perkins request...
How about adjusting the system generation a bit. Move the companion star
into the habitable orbit with your main world. Place the world in a
trojan orbit 60 degrees ahead or behind the companion star. If the
companion star is M class it should have little effect on the temperature
but the tides will be impressive.
The companion star could have a few worlds orbiting it mostly similar to
moons around a gas giant. If you wanted to justify the amber rating you
could have asteroids locked into the trojan points as well making
navigation to your main world hazardous.
If you did this you could have a thriving industry on the main world as
they sent out pilots to direct incoming and outgoing ships through the
asteroids.
