Magnetized Bondi Accretion: Here's What it Is and How We Used It
by Magnetosphere: Maintaining Habitability on EarthMay 10th, 2024
Too Long; Didn't Read
Accretion flows in galactic nuclei involve magnetized plasma, and it has been long known that magnetic fields strongly perturb the energetics (Shvartsman 1971; Meszaros 1975) and dynamics (Igumenshchev & Narayan 2002; Pen et al. 2003; Lalakos et al. 2022) of Bondi accretion.

4. MAGNETIZED BONDI ACCRETION
Accretion flows in galactic nuclei involve magnetized plasma, and it has been long known that magnetic fields strongly perturb the energetics (Shvartsman 1971; Meszaros 1975) and dynamics (Igumenshchev & Narayan 2002; Pen et al. 2003; Lalakos et al. 2022) of Bondi accretion.
Apart from a toy model with purely radial magnetic field and a non-spinning BH, where no dynamical interaction occurs between the fluid and the magnetic field (Gammie et al. 2003), there is no known analytical solution to the magnetized accretion problem. It can be studied only via numerical simulations. Our computational technique is well-suited for this.
