Hello,
A question to all you physics people - I have generated a system
for 2300AD. One of the planets came out a gas giant. But this one seems to
be the mommy and daddy of all gas giants.
Will planet A-VI ignite?
A second question refers to the habitable planets. How does one
calculate the length of the local day (i.e. rotation speed) of a given
planet, and its temperature ranges? In the data below I just decided on
arbitrary values.
System data enclosed below:

Primary (G8V) Secondary (M0V)
Magnitude: 6.12 9.28
