Remote Surveys
Remote surveys are conducted at extremely distant ranges. Since the early 20th century on Earth, astronomers have been able to determine from afar the basic characteristics of a star, such as type, mass, chemical composition. When a chart of a sector is first prepared, the location and types of stars are presumed to come from a database compiled from prior observations.
| Determine star fields | |
|---|---|
| Step A: Roll 1d100 | |
| 01 – 73 | empty space |
| 74 – 82 | possible unusual item (go to Step B) |
| 83 – 00 | star system (go to Table 2) |
| Alternate Step A: Roll 1d100 | (for when object positions are already known) |
| 01 - 33 | possible unusual item (go to Step B) |
| 34 - 00 | single star system (go to Table 2) |
| Step B - Unusual Item: Roll 1d100 | |
| 01 – 17 | unusual item (Table 3) |
| 18 – 59 | binary star system (Table 2, roll for largest)Note 1 |
| 60 – 87 | trinary star system (Table 2, roll for largest)Note 1 |
| 88 – 00 | quadruple star system (Table 2, roll for largest)Note 1 |
- Note 1: Then roll for next star(s); re-roll any that are larger (in mass) than the immediate previous largest. All successive stars must either be equal to or smaller than the preceding stars. The Spectral Class table has the necessary details.
| Step A: Roll 1d10 | |
| 01 - 02 | Non-Main Sequence star |
| 03 – 10 | Main Sequence star |
| Step B - Non-Main Sequence: Roll 1d100 | |
| 01 – 77 | Class W brown dwarfNote 2 |
| 78 - 86 | Class D white dwarf |
| 87 - 93 | IR Sequence star (go to Step D) |
| 94 - 98 | Class Z1 stellar blackhole |
| 99 - 00 | Class Z2 intermediate mass blackhole |
| Step C - Main Sequence (Simple): Roll 1d100 | (Alternate: detailed Spectral Class table) |
| 01 - 10 | Class M “Red” |
| 11 - 30 | Class K “Orange” |
| 31 - 55 | Class G “Yellow” |
| 56 - 75 | Class F “Yellowish-white” |
| 76 - 87 | Class A “White” |
| 88 - 95 | Class B “Blue-white” |
| 96- 00 | Class O “Blue” |
| Step D - IR Sequence: Roll 1d6 | |
| 01 – 02 | Class C “Red/IR” |
| 03 – 04 | Class S “Infrared” |
| 05 – 06 | Class X “X-Ray” |
- Note 2: When brown dwarfs are the result of the roll for the primary star type determination, re-roll starting with Step A. Brown dwarfs may fill the role of a secondary or later star in a multi-star system, with a solar mass of (1d8 / 100), though they will be placed within a planetary orbit, replacing the otherwise largest planet, rather than as a member of a binary pair orbiting a common center of gravity..
