A critical review of recent GAIA wide binary gravity tests
X. Hernandez, Kyu-Hyun Chae, A. Aguayo-Ortiz
Over the last couple of years, the appearance of the third data release from the {\it Gaia} satellite has triggered various wide binary low acceleration gravity tests. Wide binarie…
Statistical analysis of the gravitational anomaly in {\it Gaia} wide binaries
X. Hernandez, V. Verteletskyi, L. Nasser +1
The exploration of the low acceleration regime, where m s is the acceleration scale of MOND around which gravitational anomalies at gala…
A new hydrodynamic spherical accretion exact solution and its quasi-spherical perturbations
X. Hernandez, L. Nasser, A. Aguayo-Ortiz
We present an exact spherical accretion solution which modifies the Bondi boundary condition of as to as . This change al…
Spherical accretion: Bondi, Michel and rotating black holes
Alejandro Aguayo-Ortiz, Emilio Tejeda, Olivier Sarbach +1
In this work we revisit the steady state, spherically symmetric gas accretion problem from the non-relativistic regime to the ultra-relativistic one. We first perform a detailed co…
Choked accretion onto a Kerr black hole
Alejandro Aguayo-Ortiz, Olivier Sarbach, Emilio Tejeda
The choked accretion model consists of a purely hydrodynamical mechanism in which, by setting an equatorial to polar density contrast, a spherically symmetric accretion flow transi…
Choked accretion: from radial infall to bipolar outflows by breaking spherical symmetry
Alejandro Aguayo-Ortiz, Emilio Tejeda, X. Hernandez
Steady state, spherically symmetric accretion flows are well understood in terms of the Bondi solution. Spherical symmetry however, is necessarily an idealized approximation to rea…
Choked accretion onto a Schwarzschild black hole: A hydrodynamical jet-launching mechanism
Emilio Tejeda, Alejandro Aguayo-Ortiz, X. Hernandez
We present a novel, relativistic accretion model for accretion onto a Schwarzschild black hole. This consists of a purely hydrodynamical mechanism in which, by breaking spherical s…
Relativistic wind accretion on to a Schwarzschild black hole
Emilio Tejeda, Alejandro Aguayo-Ortiz
We present a novel analytic model of relativistic wind accretion on to a Schwarzschild black hole. This model constitutes a general relativistic extension of the classical model of…
A direct primitive variable recovery scheme for hyperbolic conservative equations: the case of relativistic hydrodynamics
A. Aguayo-Ortiz, S. Mendoza, D. Olvera
In this article we develop a Primitive Variable Recovery Scheme (PVRS) to solve any system of coupled differential conservative equations. This method obtains directly the primitiv…
