  • Taroyan, Y.; Erdélyi, R. (2008-09-01)
    The upward propagation of linear acoustic waves in a gravitationally stratified solar atmosphere is studied. The wave motion is governed by the Klein Gordon equation, which contains a cutoff frequency introduced by ...
  • Pintér, Balázs; Erdélyi, R.; Goossens, M. (2007-04)
    The coupling of solar global acoustic oscillations to a magnetised solar atmosphere is studied here. The solar interior - atmosphere interface is modelled by a non-magnetic polytrope interior overlayed by a planar atmosphere ...

  • Taroyan, Y.; Erdélyi, R. (2009-12-01)
    The heating of the solar atmosphere is a fundamental problem of modern solar and astrophysics. A review of the seismological aspects of magnetohydrodynamic (MHD) waves with an emphasis on standing longitudinal waves in the ...
  • Erdélyi, R.; Taroyan, Youra (2008-10-03)
    Context: Waves offer a unique opportunity to understand and diagnose the properties of the solar coronal plasma. Aims: Hinode/EIS observations are analysed to detect wave and oscillatory motions in the solar corona. Methods: ...
  • Taroyan, Y.; Erdélyi, R. (2010)
    Analyzing the structure of solar coronal loops is crucial to our understanding of the processes that heat and maintain the coronal plasma at multimillion degree temperatures. The determination of the physical parameters ...
  • Taroyan, Y.; Erdélyi, R.; Bradshaw, S. J. (2011-04)
    It has been established that small scale heating events, known as nanoflares, are important for solar coronal heating if the power-law distribution of their energies has a slope α steeper than −2 (α<−2). Forward modeling ...
  • Pintér, Balázs; New, R.; Erdélyi, R. (EDP Sciences, 2001-10)
    In the present paper the splitting of sectoral (m=+/- l) helioseismic eigenmodes (f- and p-modes) is studied in the presence of a magnetic atmosphere. The solar interior is in a steady state, with sub-photospheric plasma ...
