Abstract
Numerical experiments on compressible magnetoconvection reveal a new t ype of periodic oscillation, associated with alternating streaming mot ion. Analogous behaviour in a Boussinesq fluid is constrained by extra symmetry. A low-order model confirms that these pulsating waves appea r via a pitchfork-Hopf-gluing bifurcation sequence from the steady sta te.
