abstract

The special Buchdahl-inspired metric obtained in a recent paper [Phys. Rev. D 107, 104008 (2023)] describes asymptotically flat spacetimes in pure $\mathcal{R}^{2}$ gravity. The metric depends on a new (Buchdahl) parameter $\tilde{k}$ of higher-derivative characteristic, and recovers the Schwarzschild metric when $\tilde{k}=0$. It is shown that the special Buchdahl-inspired metric supports a two-way traversable Morris-Thorne wormhole for $\tilde{k}\in(-1,0)$ in which case the Weak Energy Condition is formally violated, a naked singularity for $\tilde{k}\in(-\infty,-1)\cup(0,+\infty)$, and a non-Schwarzschild structure for $\tilde{k}=-1$.

    The Buchdahl-inspired metric shifts the ISCO inward for positive k tilde and produces QPO and disk profiles that the authors fit to microquasar data, claiming 0.03<k<0.19.
