Formal stability analysis for the recent $γ = 5/3$ power-law spherical accretion solution

X. Hernandez, L. Nasser, P. L. Rendon

Recently, an exact spherically symmetric analytic accretion solution was presented having simple $ρ \propto R^{- 3/2}$ and $V \propto R^{- 1/2}$ scalings in Hernandez et al. (2023). I…

A new hydrodynamic spherical accretion exact solution and its quasi-spherical perturbations

X. Hernandez, L. Nasser, A. Aguayo-Ortiz

We present an exact $γ = 5/3$ spherical accretion solution which modifies the Bondi boundary condition of $ρ \to co n s t .$ as $r \to \infty$ to $ρ \to 0$ as $r \to \infty$ . This change al…

The massive elliptical galaxy NGC 4649 from the perspective of extended gravity

M. A. Jimenez, G. Garcia, X. Hernandez

Elliptical galaxies are systems where dark matter is usually less necessary to explain observed dynamics than in the case of spiral galaxies, however there are some instances where…
