Linear magnetosonic waves in solar wind flow tubes

TL;DR

This paper critiques previous studies on linear magnetosonic waves in solar wind flow tubes, clarifying the nature of the slab geometry and questioning the reliability of earlier results on body waves.

Contribution

It clarifies the geometric assumptions in prior work and highlights discrepancies and reliability issues in earlier analyses of magnetosonic waves.

Findings

Previous work misrepresented the slab as two-dimensional.

Results for body waves in earlier studies are unreliable.

Clarification of the slab geometry in wave analysis.

Abstract

Nakariakov et al. (1996) investigated the linear magnetosonic waves trapped within solar wind flow tubes, where they accounted for a slab having boundaries at $x = \pm d$ and extended up to infinity in the $y$ and $z$ directions. Srivastava and Dwivedi (2006) claimed to extend that work by considering a two-dimensional slab. We find that the work of Srivastava and Dwivedi (2006) is not for a two-dimensional slab and has a number of discrepancies. Further, their results for body waves are not reliable.
