Properties of Gravitationally Bound Dark Compact Ultra Dense Objects

TL;DR

This paper explores theoretical properties of ultra-dense dark matter objects, detailing their structure, stability, and potential observational signatures during collisions with visible matter.

Contribution

It introduces a new class of compact dark matter objects with specific mass ranges and analyzes their physical characteristics and collision signatures.

Findings

Maximum stable masses are sub-planetary, similar to asteroids.

Radii are on the micron to centimeter scale.

Surface gravity and tidal forces are significant for collision signatures.

Abstract

We consider compact astrophysical objects formed from dark matter fermions of mass 250 GeV to 100 TeV or from massless fermions hidden by vacuum structure of similar energy scale. These macroscopic objects have maximum stable masses of sub-planetary scale (asteroids) and radii of micron to centimeter scale. We describe the surface gravity and tidal forces near these compact ultra dense objects, as pertinent to signatures of their collisions with visible matter objects.
