Table 3.
Fast and slow magnetoacoustic gravity waves (modified version of Table 4 in Bogdan et al. 2003).
| Plasma | Fast wave | Slow wave |
|---|---|---|
| High-βvA < cS | Acoustic-gravity wave, phase speed: cs, quasi-longitudinal* | Guided along B, phase speed: vA, transverse |
| Low-βcS < vA | Magneto-sonic wave, phase speed: vA, quasi-longitudinal* | Guided along B, phase speed: cs, longitudinal |
Notes. * Quasi-longitudinal: The wavevector k is partly aligned with the plasma velocity u. The deviation between k and u generally depends on the angle between k and B.
