  • FAST MAGNETIC TWISTER AND PLASMA PERTURBATIONS IN A THREE-DIMENSIONAL CORONAL ARCADE 
    Murawski, K.; Srivastava, A. K.; Musielak, Z. E. (Institute of Physics Publishing, 2014-05-16)
    We present results of three-dimensional (3D) numerical simulations of a fast magnetic twister excited above a foot-point of the potential solar coronal arcade that is embedded in the solar atmosphere with the initial ...
  • Impulsively Generated Linear and Non-Linear Alfvén Waves in the Coronal Funnels 
    Chmielewski, P.; Srivastava, A.K.; Murawski, K.; and et. al. (Polska Akademia Nauk, 2013-12-01)
    We present simulation results of the impulsively generated linear and non-linear Alfvén waves in the weakly curved coronal magnetic ffux-tubes (coronal funnels) and discuss their implications for the coronal heating and ...
  • Magnetic swirls and associated fast magnetoacoustic kink waves in a solar chromospheric flux tube 
    Murawski, K.; Kashyap, P.; Srivastava, A.K.; Pascoe, D.J.; Jelínek, P.; Kúzma, B.; Fedun, V. (Oxford University Press, 2018-02)
    We perform numerical simulations of impulsively generated magnetic swirls in an isolated flux tube that is rooted in the solar photosphere. These swirls are triggered by an initial pulse in a horizontal component of the ...
  • NUMERICAL SIMULATIONS OF IMPULSIVELY GENERATED ALFVEN´ WAVES IN SOLAR MAGNETIC ARCADES 
    Chmielewski, P.; Murawski, K.; Musielak, Z. E.; Srivastava, A. K. (Institute of Physics Publishing, 2014-09-03)
    We perform numerical simulations of impulsively generated Alfvén waves in an isolated solar arcade, which is gravitationally stratified and magnetically confined. We study numerically the propagation of Alfvén waves along ...
  • On Thermal-Pulse-Driven Plasma Flows in Coronal Funnels as Observed by the Hinode/EUV Imaging Spectrometer (EIS) 
    Srivastava, A.K.; Konkol, P.; Murawski, K.; and et. al. (Kluwer Academic Publishers, 2014-08-21)
    Using one-arcsecond-slit-scan observations from the Hinode/EUV Imaging Spectrometer (EIS) on 5 February 2007, we find the plasma outflows in the open and expanding coronal funnels at the eastern boundary of AR 10940. The ...
  • Rotating network jets in the quiet Sun as observed by IRIS 
    Kayshap, P; Murawski, K.; Srivastava, A.K.; Dwivedi, B.N. (EDP Sciences, 2018)
    Aims. We perform a detailed observational analysis of network jets to understand their kinematics, rotational motion, and underlying triggering mechanism(s). We analyzed the quiet-Sun (QS) data. Methods. IRIS high-resolution ...
  • Spectroscopic observations and modelling of impulsive Alfvén waves along a polar coronal jet 
    Jelínek, P.; Srivastava, A. K.; Murawski, K.; Kayshap, P.; Dwivedi, B. N. (EDP Sciences, 2015-07-12)
    Context. The magnetic reconnection in the solar corona results in impulsively generated Alfvén waves, which drive a polar jet. Aims. Using the Hinode/EIS 2" spectroscopic observations, we study the intensity, velocity, and ...
  • Torsional Alfvén waves in solar magnetic flux tubes of axial symmetry 
    Murawski, K.; Solov’ev, A.; Musielak, Z. E.; and et al (EDP Sciences, 2015-05-01)
    Aims. Propagation and energy transfer of torsional Alfvén waves in solar magnetic flux tubes of axial symmetry is studied. Methods. An analytical model of a solar magnetic flux tube of axial symmetry is developed by ...
  • Two-fluid numerical model of chromospheric heating and plasma outflows in a quiet-Sun 
    Murawski, K.; Musielak, Z.E.; Poedts, S.; Srivastava, A.K.; Kadowaki, L. (Springer Science and Business Media B.V., 2022-11)
    Purpose: This paper addresses long-standing solar physics problems, namely, the heating of the solar chromosphere and the origin of the solar wind. Our aim is to reveal the related mechanisms behind chromospheric heating ...
  • Two-fluid Numerical Simulations of Solar Spicules 
    Kuźma, B.; Murawski, K.; Kayshap, P.; Wójcik, D.; Srivastava, A.K.; Dwivedi, B.N. (Institute of Physics Publishing, 2017-11-10)
    We aim to study the formation and evolution of solar spicules by means of numerical simulations of the solar atmosphere. With the use of newly developed JOANNA code, we numerically solve two-fluid (for ions + electrons and ...
  • Two-fluid Numerical Simulations of the Origin of the Fast Solar Wind 
    Wójcik, D.; Kuźma, B.; Murawski, K.; Srivastava, A.K. (Institute of Physics Publishing, 2019-10-20)
    With the use of our JOANNA code, which solves radiative equations for ion + electron and neutral fluids, we perform realistic 2.5D numerical simulations of plasma outflows associated with the solar granulation. These ...
