The magnetohydrodynamical system in bounded non smooth domains of dimension $n\ge3$

Existence of mild solutions for the magnetohydrodynamical system in C 1 domains is establishedin critical spaces in dimension n ≥3. The proof relies on recent regularity results on the Stokesoperator in C 1 domains and a Leibniz-like formula for ...

Cosmic-Ray Feedback on Bistable Interstellar Medium Turbulence

The Astrophysical Journal
While cosmic rays ( E ≳ 1 GeV) are well coupled to a galaxy’s interstellar medium (ISM) at scales of L > 100 pc, adjusting stratification and driving outflows, their impact on small scales is less clear.

Forming Prominences Accounting for Partial Ionization Effects

The Astrophysical Journal
One of the most striking structures in the solar atmosphere are prominences, predominantly coronal structures, with thermodynamic conditions that vary from chromospheric internally to the corona that surrounds them.

Magnetohydrodynamic Simulation of a Coronal Mass Ejection Observed during the Near-radial Alignment of Solar Orbiter and Earth

The Astrophysical Journal
Interplanetary coronal mass ejections (ICMEs) are the primary sources of geomagnetic storms at Earth. The negative out-of-ecliptic component ( B _z ) of magnetic field in the ICME or its associated sheath region is necessary for it to be geoeffective ...

The magnetohydrodynamical system in bounded $C^1$ domains of dimension $n\ge3$

Existence of mild solutions for the magnetohydrodynamical system in C 1 domains is establishedin critical spaces in dimension n ≥3. The proof relies on recent regularity results on the Stokesoperator in C 1 domains and a Leibniz-like formula for ...

Radiative Cooling Changes the Dynamics of Magnetically Arrested Disks

The Astrophysical Journal Letters
We study magnetically arrested disks (MADs) around rotating black holes (BHs) under the influence of radiative cooling. We introduce a critical value of the mass accretion rate ${\dot{M}}_{{\rm{crit}}}$ for which the cooling by the synchrotron process ...

3D Relativistic MHD simulations of the gamma-ray binaries [PDF]

In gamma-ray binaries neutron star is orbiting a companion that produces a strong stellar wind. We demonstrate that observed properties of stellar wind - pulsar wind interaction depend both on the overall wind thrust ratio, as well as more subtle ...
