Re: Determining the Qualities of Stars
Why not just use G-type main sequence stars? It is easier if you can connect Sol.

For the purposes of the setting, only the aetheric systems really matter. Earth is a distant theocracy on a 5-year communication delay, while the Malakim are a threat that can somehow enter - and apparently exit - hyperspace without being at an aetheric heliopause, although not reliably. Nobody can visit Earth (and while Earth occasionally sends new colonists - primarily to further along the Caliphate's spread into Harpyia so it can seize power and force humanity to return to Earth - said colonists are still a few generations removed from anyone who's actually seen Earth), and hitching a ride on one of the Malakim's biological ships to see where they are based is impossible (it will detect you, and if you kill all of its crew and prevent it from making more, it's more likely to just stay in hyperspace long enough for the aether to kill it than try to return home).

A G0 probably has at least a little more acivity than a G2 though I know of no one who has collected data on this. It' hard for me to say evven in theory what having your star in a colder but thicker interstellar medium might do. My intuition gives a 60/40 chances that it might push the heliopause farther out. Combine that witht he bigger star and the heliopause might be a long way out though you have to go about 100 ly before you're out of the bubble. I'm not even sure what the "official" distance for our heliopause is. There ahve been announcemnts that the Voyager probes have crossed the heliopause 3 or 4 times in my lifetime. It's definitely a long way out. If it was 80 AU that'd be about a month at 1G and turnover velocity would be enormous. WMD issues are a definite thing and a drive that can do it makes STL interstellar flight pretty reasonable.

One thing I intend to use the heliopause distance to determine is actually the speed of the pseudovelocity boost drives - I want a typical freighter to take roughly 1 month to go from 1.11 AU to the heliopause, making interstellar journeys typically take 2 months, plus the time in hyperspace. With my initial estimate of 88 AU for the heliosphere, that's 86.89 AU per month, or right around 3000 mps. That's roughly Earth's solar orbit to Mars' solar orbit in 4 hours, 20 minutes (or Gateway to the next furthest orbit in 6 hours, 20 minutes).

Re: Determining the Qualities of Stars
Are you using real stellar data for position etc.? If so, are you aware of the Extended Hipparcos compilation of stellar data? I find it pretty useful.
I count 295 G0V stars within 200 light-years.

Re: Determining the Qualities of Stars
άρπυια is a first-declension feminine noun ending in -α. I think the genitive is άρπυιασ. "Harpyias".

I thought that might be the case, actually. I'll probably change it to Harpyias Mati, then.
