Accretion Flow onto Ellis–Bronnikov Wormhole

Study of accretion onto wormholes is rather rare compared to that black holes. In this paper, we consider flow cosmological dark energy modeled by barotropic fluid the celebrated Ellis–Bronnikov wormhole (EBWH) built Einstein minimally coupled scalar field ?, violating null condition. The accreting assumed be phantom, quintessence, dust and stiff matter. We begin first pointing out a mathematical novelty showing how EBWH can lead Schwarzschild hole under complex Wick rotation. Then, analyze profiles radial velocity, density rate mass variation due compare with those hole. also massless has zero ADM but what call nonzero Wheelerian (“mass without mass”), composed non-trivial field, shows gravitational effects. Our conclusion SBH phantom decreases consistently known results, while, in contrast, increases. Exactly an opposite behavior emerges for non-phantom these two objects. Accretion (i.e., mass) shares same patterns as massive EBWH; hence there no way distinguish cases means flow. contrasting variations could reflection distinct topology central
