Star Types
Every star in a Dyson Sphere Program cluster belongs to a spectral type that determines its luminosity, temperature, Dyson Sphere output, and the kind of planets and resources you are likely to find around it. The table below compares all star types at a glance so you can pick where to expand next.
star-type
star a main sequence
Class ADescription
White-blue main-sequence star, more luminous than the Sun.
star b main sequence
Class Bstar black hole
Black HoleDescription
A black hole. Same orbital extreme matter as Neutron Star, end-game farming target.
star blue giant
blue_giantstar f main sequence
Class Fstar g main sequence
Class GDescription
Sun-like yellow main-sequence star. Standard system with terrestrial planets.
star k main sequence
Class KDescription
Orange main-sequence star, cooler than G-type.
star m main sequence
Class MDescription
Red dwarf main-sequence star. Common but low-luminosity.
star red giant
M GiantDescription
An evolved star expanded into a red giant. Strong solar wind, less suitable for Dyson Sphere construction.
star neutron star
Neutron StarDescription
Ultra-dense stellar remnant. Drops Strange Matter and Critical Photons, end-game key resource.
star o main sequence
Class Ostar white dwarf
White DwarfDescription
A stellar remnant. Drops Unipolar Magnet, a key resource for end-game research.
