Modeling multiphase plasma in the corona: prominences and rain

open access: yesLiving Reviews in Solar Physics
We review major achievements in our understanding of multiphase coronal plasma, where cool-dense and hot-tenuous matter coexists, brought about by advances in modeling and theory, inspired by observations.

Dynamics, thermodynamics, and fine structure of virtual erupting filaments

open access: yesAstronomy & Astrophysics
Context. It is not fully understood why some solar filaments erupt, whereas others do not. Filaments that erupt typically undergo a slow rise, followed by an acceleration phase; this transition requires further investigation.

Free–Free Gaunt Factors for Atmospheres of Accreting Pulsars Observable with X-Ray Space Missions

open access: yesThe Astrophysical Journal
Free–free Gaunt factors for X-ray absorption by hot plasma in the presence of a strong magnetic field are reported. Modified formulae are used for application to the nonlocal thermodynamic equilibrium conditions found in accreting pulsar atmospheres ...

Whistler–Alfvén Turbulence in a Nonneutral Ultrarelativistic Pair Plasma

open access: yesThe Astrophysical Journal
The large-scale dynamics of most conventional space and astrophysical plasmas are predominantly governed by Alfvén modes, which are low-frequency magnetohydrodynamic modes existing in magnetized media.

The usage of numerical code FLASH in plasma astrophysics

open access: yes, 2013
My diploma thesis is focused on the use of numerical computer codes for simulation in plasma astrophysics. They will learn the basic characteristics of the Sun, a closer focus on the solar corona and the solar corona heating problem.

Velocity-space Origins of the Pressure–Strain Interaction in Multipopulation Distributions and Its Application to Magnetic Reconnection

open access: yesThe Astrophysical Journal
A forefront research question is how energy evolves in weakly collisional plasmas for which departures from local thermodynamic equilibrium (LTE) are significant.
