Onkoletteita

Onkoletteita is a term used to describe a specific type of hypothetical celestial object that is thought to possess characteristics of both a neutron star and a black hole, but without crossing the event horizon. The concept arises from theoretical models that explore the extreme physics of dense matter. If a neutron star were to accrete enough mass to exceed the Tolman-Oppenheimer-Volkoff limit, it would typically collapse into a black hole. However, some theories suggest that under certain conditions, the object might stabilize in a state where it is extremely dense but still has a surface, thus preventing the formation of an event horizon.

These theoretical objects would be incredibly compact and possess immense gravitational fields. Their internal structure is a subject of ongoing research and debate, with various models proposing different states of matter, such as hyperons or deconfined quarks. Detecting an onkoletta would be challenging due to their extreme density and likely small size. However, their presence could potentially be inferred through their gravitational influence on surrounding matter or by observing unique emission signatures if any matter were to fall onto their surface. The term itself is a neologism combining elements of "onko" (perhaps, maybe) and "koletta" (a hypothetical compact object), reflecting its speculative nature. Further theoretical work and potential future observational advancements are needed to determine if such objects exist in the universe.
