    • Ion acoustic solitons in dense magnetized plasmas with nonrelativistic degenerate electrons and positrons 

      Sadiq, Safeer; Mahmood, Shahzad; Haque, Q.; Ali, Munazza Zulfiqar (2014) [Journal article]
      The propagation of electrostatic waves in a densemagnetized electron–positron–ion (EPI) plasma with nonrelativistic and ultrarelativistic degenerate electrons and positrons is investigated. The linear dispersion relation ...
    • Nonlinear evolution of beam-plasma instability in inhomogeneous medium 

      Ziebell, Luiz Fernando; Yoon, Peter H.; Pavan, Joel; Gaelzer, Rudi (2011) [Journal article]
      The problem of electron-beam propagation in inhomogeneous solar wind is intimately related to the solar type II and/or type III radio bursts. Many scientists have addressed this issue in the past bymeans of quasi-linear ...
    • On the counterpropagation of waves 

      Nunes, Roger Pizzato; Gerhardt, Gunther Johannes Lewczuk; Rizzato, Felipe Barbedo (2019) [Journal article]
      This work analyses the counterpropagation of transversal plane waves in a linear, homogeneous, nondispersive, and isotropic medium. Although this is a traditional subject in disciplines associated with wave phenomena, a ...
    • Particle-in-cell and weak turbulence simulations of plasma emission 

      Lee, Sang-Yun; Ziebell, Luiz Fernando; Yoon, Peter H.; Gaelzer, Rudi; Lee, Ensang (2019) [Journal article]
      The plasma emission process, which is the mechanism for solar type II and type III radio burst phenomena, is studied by means of particle-in-cell (PIC) and weak turbulence (WT) simulation methods. “Plasma emission” is meant ...
    • Plasma emission by counter-streaming electron beams 

      Ziebell, Luiz Fernando; Petruzzellis, Larissa Teixeira; Yoon, Peter H.; Gaelzer, Rudi; Pavan, Joel (2016) [Journal article]
      The radiation emission mechanism responsible for both type-II and type-III solar radio bursts is commonly accepted as plasma emission. Recently Ganse et al. suggested that type-II radio bursts may be enhanced when the ...
    • Plasma emission by nonlinear electromagnetic processes 

      Ziebell, Luiz Fernando; Yoon, Peter H.; Petruzzellis, Larissa Teixeira; Gaelzer, Rudi; Pavan, Joel (2015) [Journal article]
      The plasma emission, or electromagnetic (EM) radiation at the plasma frequency and/or its harmonic(s), is generally accepted as the radiation mechanism responsible for solar type II and III radio bursts. Identification and ...
    • Solar wind strahl broadening by self-generated plasma waves 

      Pavan, Joel; Figueroa Viñas, Adolfo; Yoon, Peter H.; Ziebell, Luiz Fernando; Gaelzer, Rudi (2013) [Journal article]
      This Letter reports on the results of numerical simulations which may provide a possible explanation for the strahl broadening during quiet solar conditions. The relevant processes involved in the broadening are due to ...
    • A theory of the fundamental plasma emission of type-III solar radio bursts 

      Alves, Maria Virginia; Chian, Abraham Chian-Long; Moraes, Márcio A.E. de; Abalde, José Ricardo G.; Rizzato, Felipe Barbedo (2002) [Journal article]
      Results from plasma wave experiments in spacecraft give support to nonlinear interactions involving Langmuir waves, electromagnetic waves and ion-acoustic waves in association with type III solar radio bursts. In this paper ...
