Sirius Sector (-9,-6,0)

Sirius is Kline’s innermost (with respect to Sol) sector and the Duke of Sirius is the seat of Kline’s power, when, of course, they don’t already control the Emperor’s throne.

The significant population centres are Sirius and Procyon, as both are close binaries, the large habitats occupy the stable orbits at great distances from the stellar members.

Sirius

The Sirius System consists of a very bright A type primary member, with the white dwarf Sirius B eccentrically orbiting at an average distance of 7.4 AU. The tight eccentric orbits, combined with the mass and orbit redistribution, following the supernova of the (previously B5-type) Sirius B, has completely removed all planets from the system. Although a large amount of interstellar dust (and some of the supernova ejecta) has contributed to a secondary dust ring located between 12 and 25 AU.

There are more than 60 O’Neill cylinder habitats orbiting the Sirius system, centring on 30 AU distance from the pair. All of these have spaceports for inter-habitat and interstellar travel. The habitat constituting the capital, Sirius Prime, is however restricted, and no one playing Striker will have a character important enough to be allowed to land there.

Emhoff

Emhoff typifies the early dark mining colony, the star is an extremely dim brown dwarf, which throws very little light. The power therefore comes from then many fusion reactors that power small habitats, research stations and other lonely industrial facilities.

The high metallicity of the system means that there is a huge amount of material, which has maintained the viability of Emhoff as a mining colony, despite the riches provided by the Ophiuchi Reaches.

Fortuna

Fortuna is the priciple mining and industrial location of the Sirius Sector. This has really only been a reality in the last 300 years, because of the inability of the ancients to negotiate the hazards of the system.

The main hazard is the intensely flaring red dwarf star, which flares powerfully enough to disrupt electronics, and kill people in aegis suits. The other is bombardment from the many planetesimals flying around the vast terrestrial belt of this system.

The habitats of the system lay beyond the snowline, because of these hazards.

This vast belt is both a hazard, but also the source of its riches. A steady effort is maintained in tracking and predicting the movements of these rocky projectiles, so as to calculate mining windows at, and navigation paths to, any given location.

Also, solar collectors are located on the inner-most chunks of rock and systems of cable route that power to the dark sides of these rocks, and it gets beamed out to the habitats. Other power is supplemented by antimatter or higgs reactors.

Luyten’s Star

Luyten’s Star is an old, but quite high metallicity red dwarf, and has a complete system of planets, including a large terrestrial system, with some high mass members.

Of particular note are Thedia, which is a tidally-locked 2.89 earth mass planet with a broad habitable ring, and the huge 10.8 earth mass Tiro, under 2.15 G, but with 5 times the surface area of Earth. Naturally, the population of Tiro are shorter and stockier than most humans, and this load takes quite some getting used to for the recent immigrant. Its also quite dark on Tiro, the combination of feeble light from Luytens Star and thick atmosphere, ensures that its never brighter than an extremely overcast day. Freens, if they could ever be allowed to get to a place like this, would quite like it.

Procyon

Procyon has a similar arrangement with respect to habitats as Sirius, though on a smaller scale. The primary member of Procyon is much dimmer and experiences quite a bit of instability. One result is that the habitats are built with a lot more electromagnetic shielding, and any direct sunlight is avoided or heavily filtered.

Reeve

Reeve is similar in form and usage to Emhoff. It is both a smaller system overall and its is an older mining colony. A lot of its activity is dropped off, and it functions, for most people, as a waystation these days.

Ross 614

Ross 614 consists of an intensely flaring red dwarf star with a closely orbiting, much smaller star laying at the red dwarf, brown dwarf boundary. For the purposes of this system, the brown dwarf acts as a (90-jupiter-mass) large planet, while it has cleaned out all terrestrials from the system, grabbing a few of them as moons, much of the icy material has remained.

Much of the mining activity is on the many moons of Ross 614B. The very small red star has tidally locked many of the inner planetesimals and material. Its intense magnetic field also shields a lot of the moons from the worst of the flares and magnetic storms of Ross 614A.

Ross 614 is economically an extension of the activities on Emhoff, owing to its relative close proximity.
