DESCRIPTION:Speakers: Olga Sazhina (SAI MSU)\,  Iurii Moiseev (SAI Lomonos
 ov MSU)\nWe present simulated detectability of traversable wormholes (WHs)
  in wide binary astrophysical systems without accretion (dormant binary sy
 stems) and in the Galactic center. The wormhole spacetime is represented a
 s a gluing of two asymptotically flat Schwarzschild spacetimes\, without s
 pecifying the detailed geometry of the throat. We consider a traversable W
 H candidate as a compact object in a binary system\, whose companion star 
 is perturbed by a massive object on an elliptical orbit on the other side 
 of the WHthroat. In the case of a supermassive BH as WH candidate the pert
 urbing acceleration is analyzed and compared with the stochastic gravitati
 onal influence of surrounding stars. For dormant wide binary systems\, we 
 analyze the radial velocity perturbations and their distinguishability fro
 m triple-system scenario. Under the model assumptions and the considered o
 bservational sampling\, radial velocity perturbations are detectable in si
 mulations with an observational accuracy of 1.5 km/s for all considered ob
 servation time spans. For a more conservative accuracy of 10 km/s\, the sp
 ectral analysis methods become statistically significant after ≈ 17 year
 s of simulated data accumulation. The spectral and non-parametric methods 
 significantly reduce the required accumulation time compared to matched-fi
 ltering applied in isolation.\n\nhttps://indico.particle.mephi.ru/event/62
