Date: Mon, 13 Feb 1995 12:07:13 -0500 From: Harold D. Hale Subject: Known Stars In the Solomani Rim Submitted to the light for all to behold or toss stones..... This list is the result of a lot of research, and help from the somewhat more knowledgeable (in some cases much more knowledgeable). Those who I have bugged over the past months regarding this project know who you are and I thank you. "Designer's" Notes A number of constraints were in place when I began this project. The first major one was that none of the star systems could be "moved". All the known stars had to be placed within existing star systems in the position they existed as of John Harshman's original work--this also meant that new systems could not be "created". The result is that some known stars are a bit out of place (particularly those furthest away), though the general direction to them is more or less correct. The second major constraint was that all main world stats (with the exception of those which were contrary to the rules) were "sacred". This meant that some stars had to be "turned up" a few degrees (M7 Vs made into M2 Vs, etc.) so that the world that circled them wouldn't be against the laws of astrophysics (i.e. a world with a standard, tainted atmosphere circling an M6V star). This also necessitated, in one instance, "flip-flopping" of two sets of known stars in their relative position to each other and Sol so that the main worlds were matched up with a compatible star. The third major constraint was what I call "The Uncertainty Principle" (I know the name is already taken, but it works for my purposes as well), and it reads something like: "the further you get away from Sol, the less likely you are to be correct about the exact location of any given star". While some stars could be identified beyond seven parsecs (the limit I ended establishing for myself for identifying correctly the position of known stars) because they were particularly bright or near a significant star (like Arcturus or Altair), most main sequence types beyond that limit could be placed in one of three, four, or more systems. I ended up concentrating on getting the stars closer to home right (actually more accurate), and including additional stars beyond that limit if I felt comfortable about the accuracy of their location. I welcome anyone criminally insane enough to attempt to push the boundary out further than seven parsecs (especially given the above constraints)--perhaps the nice men in the white coats will give you extra crayons for the project. Additional notes.... Some of the systems contain more than one named star--this is not necessarily because the stars in question are binary (trinary, etc.) pairs--it just so happens that they lie within one parsec of each other (particularly in the 'X' and 'Y' axis). Some stars (like Beta Hydri) are relatively close to Sol along the 'X' and 'Y' axis (2D-wise) but are a great deal further away in the third dimension (up and down, or above and below the plane of the galaxy). In those cases, the relative position of the star to Sol was "translated" so that the direction from Sol to the star remained basically the same, but the distance between Sol and the star remained the same. This allowed the galaxy to be "flatten", and expressed in Traveller terms. Send your additions, corrections, suggestions and general constructive criticism to hdhale@tasc.com. The table below will look much better in a proportional font like Courier, if you pull it up in a word processing program.

Alpha Crucis Alpha Crucis (Acrux) B1IV B3IV Some 360 l.y. distance (over 110 parsecs), it could not possibly be located in the Alpha Crucis Sector (oops!). This raises the question of whether the name of the sector should be changed. The best candidate so far that I am aware of is Alpha Leonis (Regulus) which is at least in the sector.
