The general procedure of finding the wave vectors of all possible standing MHD modes in any given point of a stationary flow requires numerically solving an algebraic equation. We present the graphical procedure (already mentioned by some authors in the 1960&rsquo;s) along with the exact solution for the Alfv\u00e9n mode and approximate analytic solutions for both fast and slow modes. The technique can be used to identify MHD modes in space and laboratory plasmas as well as in numerical simulations.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-10\" src=\"https:\/\/sites.lesia.obspm.fr\/lea-griton\/files\/2018\/03\/fig_these_standing_fast_mode-300x202.png\" alt=\"\" width=\"300\" height=\"202\" srcset=\"https:\/\/sites.lesia.obspm.fr\/lea-griton\/files\/2018\/03\/fig_these_standing_fast_mode-300x202.png 300w, https:\/\/sites.lesia.obspm.fr\/lea-griton\/files\/2018\/03\/fig_these_standing_fast_mode-768x516.png 768w, https:\/\/sites.lesia.obspm.fr\/lea-griton\/files\/2018\/03\/fig_these_standing_fast_mode-1024x689.png 1024w, https:\/\/sites.lesia.obspm.fr\/lea-griton\/files\/2018\/03\/fig_these_standing_fast_mode.png 1047w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<p>See the paper for the figure&rsquo;s legend.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Identification of standing fronts in steady state fluid flows: exact and approximate solutions for propagating MHD modes Authors: F.
