Problems in stellar hydrodynamics

Papers are presented which study the effects of rotation and magnetic fields on stellar structure and evolution, stellar stability, mass loss in stars, and dynamic phases of evolution before the main sequence. Some of the topics covered include time scales in stellar spindown, bubble stability of differential rotation, meridional circulation in magnetic stars, stability of nonlinear periodic pulsation of stellar envelopes vibrational stability of evolving stars, numerical models with overshooting of convective cores, circumstellar absorption lines and mass loss from red giants, an extremely carbon enhanced nova model, and the stability limit of plane-parallel and infinite gravitating media. Individual items are announced in this issue.
