Abstract

In the present work, we develop and examine a series of exact solutions to Einstein's 5-dimensional field equations in the vacuum, which depend on two constant parameters, pp and qq, which generalize the solutions of L\"u and Mei [8] belonging to our class p=2p=2. This category of solutions can be split into two sections: when pp is odd, it represents a compact object that may have naked singularities. However, the intriguing outcome occurs when pp is even, as asymptotically Ricci flat wormholes emerge in this scenario. The Kreschman invariant of these solutions depends on the constant parameter l=1+3q2p24l = 1 + \frac{3 q^2 - p^2}{4}. When l=0l = 0 and l12l \leq -\frac{1}{2}, the solutions are regular. For the specific cases where l0l \leq 0, or l>0l > 0 such that q<0q < 0 for p2p \geq 2, q13q \leq \frac{1}{3} for p=2p = 2, and q1+23q \leq \frac{1 + \sqrt{2}}{3} for p4 p \geq 4, this class of wormholes adheres to Wormhole Cosmic Censorship, implying that the throat effectively obscures all causal anomalies and singularities. In our analysis, we investigated the embedded geometry, geodesics, singularities, potential event horizons, ergoregions, and the wormhole throat.
