Forthcoming articles have been peer-reviewed and accepted for publication but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

Forthcoming articles must be purchased for the purposes of research, teaching and private study only. These articles can be cited using the expression "in press". For example: Smith, J. (in press). Article Title. Journal Title.

  • Effect of kappa distribution function with temperature anisotropy through firehose instability in earths magneto-plasma   Order a copy of this article
    by Neeti Tandon, Rohit Rastogi, Ganpat Ahirwar 
    Abstract: Firehose instability (FHI) has been studied by kinetic approach with Kappa distribution function in the auroral acceleration plasma region, a part of the earths magnetosphere. The combined effect of temperature anisotropy for ions, electrons, and dust particles, which are responsible for driving firehose instability. The effect of spectral index kappa,on FHI, has been studied. The interpretation of the analytical results has been done by considering the plasma parameters of the auroral acceleration region. The results and analysis may be checked and extended to multi-component plasma. In the process of linearisation, partially changing quantities are expressed as a sum of a mean value and its first-order perturbation. Then by performing Fourier/Laplace transformation in both time and space, which converts spatial variable r, and temporal variables t, into k and , this provides fluctuating particle densities and particle flux densities, then these are inserted into Maxwells equation that further yields the dispersion relation.
    Keywords: firehose instability; FHI; temperature anisotropy; kappa distribution function; auroral acceleration region.
