hydrogenoids
Hydrogenoids are theoretical celestial objects consisting predominantly of hydrogen, the simplest and most abundant element in the universe. They are sometimes conceptualized in astrophysics as primitive or early-stage stars, or as remnants of cosmic structures primarily composed of hydrogen gas. Unlike conventional stars, which generate energy through nuclear fusion of heavier elements, hydrogenoids are generally characterized by their reliance on gravitational contraction or other processes for their energy output, if any.
The term "hydrogenoid" can also refer to certain types of artificial or simulated models used in astrophysical
In theoretical models, hydrogenoids might represent primitive stellar objects or substellar bodies that have not yet
Overall, hydrogenoids remain a largely hypothetical or conceptual category within astrophysics, primarily serving as models or
