quasi-star
Let an agent explain quasi-stars as a hypothesis, with attributed models, the evidence being sought and the difference from quasars.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

What it is Filled
A hypothetical type of very massive, extremely luminous object proposed to have existed in the early universe, in which a black hole forms in the core of a massive protostar and grows by accretion inside the surrounding envelope; proposed by astrophysicists as one route to early supermassive black holes, and not confirmed by observation.
Why it exists Filled
Let an agent explain quasi-stars as a hypothesis, with attributed models, the evidence being sought and the difference from quasars.
