Bondi Accretion onto a Damour–Solodukhin Wormhole

Year: 2025

Type: article

Abstract: The Damour–Solodukhin wormhole (hereinafter DSWH) is known to mimic a Schwarzschild black hole (hereinafter SBH) horizon in some properties. To act as a mimicker, the DSWH parameter $$\lambda$$ by definition is required to be extremely tiny, i.e., $$\lambda\sim 0$$ . Our comparative analysis shows that such a requirement may be too restrictive at least as far as the Bondi accretion profiles of the two objects, the DSWH and SBH, are concerned. Intriguingly, it turns out that some profiles of a DSWH mimic those for the SBH near the horizon even at values of $$\lambda$$ considerably higher, i.e., $$\lambda\sim 1$$ .
