Astrographic Features & Trade Routes: 1105

The following astrographic and commercial data has been determined:

Borealis Group

The subsector forms part of the Borealis Group, a gigantic, broadly spherical cluster of stars centered on Theta Borealis Sector.

• It is a distinctive, extremely bright feature that can be easily observed from all across Charted Space.
• It is more than 40 parsecs in diameter.
• It contains an unusually high number of giant stars.
• It is the density of giant stars within the region, rather than their individual brightness, that makes the feature so prominent.

The night-time skies of all of the worlds across the region are studded with a panoply of colorful, intensely bright stars.

• Some are so bright that they can be clearly seen from planetary surfaces during daylight hours.
• The brightest is Theta Borealis, an unstable, violent, blue-white bright supergiant with a luminosity of around 73,000 sols.
• Other extremely bright stars within the cluster include Sigma Borealis, Tau Borealis, Epsilon Borealis, Mu Borealis, and Kappa Borealis.
• While the cluster contains many extremely luminous giant stars, Theta B is exponentially brighter than any of the others.

Chains of giant stars trail out from the cluster into many of the surrounding sectors.

• Duhamel Subsector lies to trailing of the clusters core, forming part of a long outlying trail of giant stars.

Stellar Distribution

A basic map showing the distribution and size of stars within Duhamel Subsector.

• The color corresponds to the visible color of the star, which links to its spectral classification.
• The size as shown indicates both the physical size of the object and its relative brightness.

(Chart sourced from Traveller Map).

Note that the stars as depicted are representative. Any star, no matter what its size, is a mere speck within the hex it occupies.

• Ordinary main sequence stars can barely be seen from even a hex away.
• Huge, intensely luminous giant stars can be seen from across the subsector and far beyond.

Subsector Summary: 1105

Duhamel, subsector L of Theta Borealis contains 31 worlds with an estimated population of 119 billion, a per capita income of Cr4,664, and a total economy is BCr555,068. These worlds originate an interstellar trade of BCr861 through 26 starports (6 Class A, 5 Class B, 14 Class C, 1 Class D) employing 103,505 people. Driving this interstellar trade are eight Agricultural (Ag) worlds, two Non-Agricultural (Na) worlds, one Pre-Agricultural (Pa) world, five Pre-Industrial (Pi) worlds, two Rich (Ri) worlds, and two Industrial (In) worlds. The governments in Duhamel maintain three Scout bases, and one Naval base. The average technology level is 7 (with most between 5 and 10). The highest technology level is 13 at Storm Rider (Theta Borealis 2625).

Duhamel, subsector L of Theta Borealis contains 41 stars and 329 identified planets; 23 monostellar systems, six binary systems, two trinary systems, and no systems with four or more stars. 14 of the 31 systems (45%) have native gas giants. There are two Asteroid (As) belts, one Desert (De) world, one Garden (Ga) world, no Ice-capped (Ic) worlds, one Poor (Po) world, four Vacuum (Va) worlds, and no Water (Wa) or Ocean (Oc) worlds.

Duhamel has an estimated population of 119 billion distributed across three High population (Hi) worlds, one Moderate population (Ph) world, ten Non-industrial (Ni) worlds, nine Low population (Lo) worlds, and one Barren (Ba) world. The highest population worlds are Ratan (Theta Borealis 2822) and Dennson (Theta Borealis 3122). The population consists of 1 sophont groups.
