This is a mod sort of complimentary to either Kepler68's More Star classes, or Annatar's Real Space, that adds several new types of stars that as of now are only hypothetical and have not been detected yet.
Features:
7 new types of stars (some included in binary systems):
Antimatter star
Blue dwarf star
Black dwarf star
Dark star
Quasi-star
Strange star
White hole
6 new modifiers:
Q-star (for black holes)
Intermediate mass black hole (for black holes)
Population III star (for class M and K stars)
Thorne-Żytkow object (for red supergiants and hypergiants)
Quark Star (for neutron stars and pulsars)
Electroweak star (for neutron stars and pulsars that have the Quark Star modifier)
3 new strategic resources, with their corresponding technologies:
Strange matter, found in strange stars.
Quark-gluon plasma, found in quark stars.
Antimatter, found in antimatter stars.
3 new edicts that make use of the new strategic resources.
