abstract
In this paper I present a new class of traversable wormholes. This is done by surgically grafting two Schwarzschild spacetimes together in such a way that no event horizon is permitted to form. This surgery concentrates a non--zero stress--energy on the boundary layer between the two asymptotically flat regions. I shall investigate this stress--energy in detail using the "junction condition" formalism. A feature of the present analysis is that this class of traversable wormholes is sufficiently simple for a (partial) dynamical stability analysis to be carried out. The stability analysis places constraints on the equation of state of the exotic matter that comprises the throat of the wormhole.

Thin-shell wormholes in T-duality quantum-corrected regular spacetimes exhibit an intermediate-radius window of unconditional stability absent in the classical Schwarzschild case.
In asymmetric Damour-Solodukhin wormholes, reflectionless and echo modes share asymptotic spectral properties parallel to the real frequency axis with matching spacing, and reflectionless modes lie closer to the axis yielding larger echo amplitudes.
Analytic gravitational waveforms from radial test-particle infall into a thin-shell traversable wormhole exhibit a characteristic pulse-gap structure from repeated throat crossings and lie within reach of ground-based detectors at ~500 Mpc.
Slowly rotating wormholes in Rényi, mixed, and Moradpour holographic dark energy produce distinct photon orbits and shadow morphologies, with Rényi models yielding smaller asymmetric shadows.
The paper derives a generalized first law for thin-shell wormholes showing entropy conservation for isolated transparent shells and flux-dependent entropy change when bulk matter crosses the throat.
Black bounce spacetimes with larger throat parameter α produce enhanced periastron precession, light deflection, and a larger critical impact parameter in the wormhole regime, offering potential observational signatures.
