The goal of Dyson Sphere Program is to complete a megastructure called a Dyson Sphere around a star. Stars have six different attributes and each will affect the Dyson Sphere and its outputs in different ways. These attributes are: mass, spectral class, radius, luminosity, temperature, and age.
Attributes[]
Spectral Class[]
- O (blue)
- B (light blue/Blue Giants)
- A (blue/white)
- F (yellow)
- G (yellow)
- K (orange)
- M (red)
| Spectral Class | Image | Mass Range | Radius | Luminosity | Temperature | Age |
|---|---|---|---|---|---|---|
| O | 60 M☉ | 4-15 R☉ | 2-2.766 L☉ | Over 25,000K | 6 Myrs | |
| B | 10 M☉ | 2 R☉ (Blue Giants can be ~13.5 R☉) | 1.6 L☉ | 13,152-30,942 K | 15-242 Myrs | |
| A | 3 M☉ | 1.6 R☉ | 1.2 L☉ | 8,550-12,683K | ~135-421 Myrs | |
| F | 1.7 M☉ | 1.3 R☉ | 1.5 L☉ | 6,000-7,500K | 11,000-4700 Myrs | |
| G | 1.1 M☉ | 1.1 R☉ | 1.2 L☉ | 5,000-6,000K | ||
| K | 0.8 M☉ | 0.9 R☉ | 0.85 L☉ | 3,500-5,000K | ||
| M | 0.3 M☉ | 0.4 R☉ | .7 L☉ | Under 3,500K |
- X
- Black Hole
- Neutron Star
- White Dwarf
Notes:
The older a B Type Star gets, the less blue it appears, eventually appearing almost white.
Young B Type Stars are blue and usually much more hot and massive than the other B stars.
X subclass of stars do emit light and it is possible to build a Dyson Sphere around a black hole.
