Internal kinematics of GAIA DR3 wide binaries: anomalous behaviour in the low acceleration regime
X. Hernandez
The {\it Gaia} eDR3 catalogue has recently been used to study statistically the internal kinematics of wide binary populations using relative velocities of the two component stars,…
Formal stability analysis for the recent power-law spherical accretion solution
X. Hernandez, L. Nasser, P. L. Rendon
Recently, an exact spherically symmetric analytic accretion solution was presented having simple and 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 spherical accretion solution which modifies the Bondi boundary condition of as to as . This change al…
Internal kinematics of GAIA eDR3 wide binaries
X. Hernandez, S. Cookson, R. A. M. Cortes
Using the recent GAIA eDR3 catalogue we construct a sample of solar neighbourhood isolated wide binaries satisfying a series of strict signal-to-noise data cuts, exclusion of rando…
Asymptotic kinematics of Globular Clusters: the emergence of a Tully-Fisher relation
X. Hernandez, A. J. Lara-D.
Using a recent homogeneous sample of 40 high quality velocity dispersion profiles for Galactic globular clusters, we study the low gravitational acceleration regime relevant to the…
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…
