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

open access: yesThe 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 ...

Radiative Cooling Changes the Dynamics of Magnetically Arrested Disks

open access: yesThe 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 ...

Forming Prominences Accounting for Partial Ionization Effects

open access: yesThe 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.

Magnetic Flux Plays an Important Role during a Black Hole X-Ray Binary Outburst in Radiative Two-temperature General Relativistic Magnetohydrodynamic Simulations

open access: yesThe Astrophysical Journal
Black hole (Bh) X-ray binaries cycle through different spectral states of accretion over the course of months to years. Although persistent changes in the Bh mass accretion rate are generally recognized as the most important component of state ...
