I have built a website to automate the procedures in the Architect of Worlds book by Jon Zeigler.
The URL is: aahench.pythonanywhere.com
Star systems and 3D star maps can be randomly generated.
Every world has a map.
The output URL can be saved and shared to re-generate the same result.

WHAT IF
An intelligent species evolving here might be large, heavyset and well insulated.
Like smart polar bears, perhaps.
Ocean travel would be essential for them to expand.
Crossing frigid seas with perpetual winds and icebergs everywhere.
Imagine Viking polar bears sailing under dancing suns.

Orbits both stars.
They can be up to 10° apart from each other in the sky.
That means dual shadows at times.
The stars look smaller than our sun.
Large moon can eclipse one or both.
Slow rotation, days are over 120 hours long.
So eclipses last much longer than on Earth.
Sometimes two in one day.
