A Massive Discovery
When I started creating the back-story for Maia, earlier this year, I did a lot a research. As a fan of hard science fiction, I wanted things to be scientifically accurate or at least plausible.
My choice of star system was one of the problems I struggled with. It had to be near enough to be a feasible target for travel and with a star, near the luminosity of our own, capable of supporting life within its habitable zone.
I was drawn to Tau Ceti as its dust clouds and debris field would be a great sign for the creation of earth like planets. The more I papers I studied, the more obvious it seemed to me that there were planets hiding in among the debris.
Strangely I found that a lot of academics had decided that the system wasn't worth investigating due to the composition of its sun. With a relatively low metallicity compared to our own star, it had been assumed that a telluric planet would not form there. This meant that several chances to search for planets were missed, in light of more promising targets.
I found this and other arguments against it rather weak, and set the game in Tau Ceti anyway. I wanted to go out on a limb with this one and hoped that someone smarter than me didn't completely destroy my thinking.
