Star system 69 consists of five stars. The main binary of an A and G star orbiting with a trinary subsystem of an M, a K and brown dwarf
class star. The main binary is an Algol type star illustrating the Algol paradox that the less massive star in the system appears more
highly evolved. This is the yellow G class star which is a yellow subgiant, which is more swollen than expected for its age as if it was
evolving into a red giant already. This paradox can be explained by mass transfer. The large A class white giant evolved more rapidly,
swelling to fill its Roche lobe (RL) and transferring massive amounts of mass, very efficiently, to its yellow dwarf companion by
Roche-lobe overflow. Thus, the A star lost much of its mass whilst the yellow dwarf gained mass to become a yellow subgiant with a
large radius, almost as large as that of its white giant companion.
This has resulted in the semi-detached binary we see today (semi-detached because the a star still fills its Roche lobe) with a rotational
period of 18.24 days. This system has no planets, presumably the complex orbital dynamics caused the planets to be shed into deep
space long ago.
Recommendation: conduct a full sensor sweep of the stars in this system for later analysis and then
Set a course for a new target system
