We consider mixed strongly gravitating configurations consisting of a wormhole threaded by two types of ordinary matter. For such systems, the possibility of obtaining static spherically symmetric solutions describing compact massive central objects enclosed by high-redshift surfaces (black-hole-like configurations) is studied. Using the standard thin accretion disk model, we exhibit potentially observable differences allowing to distinguish the mixed systems from ordinary black holes with the same masses.

  1. Mass--radius relations, surface redshift, and echo time of neutron-star--wormhole system with chaotic magnetic field and anisotropic matter

    gr-qc 2025-12 reject novelty 5.0

    Anisotropic magnetized neutron-star–wormhole models predict ultracompact objects with masses above 8 solar masses, surface redshifts above 1.5, and echo times of order 10^-2–10^-1 ms.
