It is found tl-lat when the pressure on axis is zero, a continuous spectrum arises, which may become unstable. When the pressure on axis is finite or a conducting core is included, the spectrum is discrete, but may still be unstable. The instability is due to the poloidal magnetic field and/or the rotation of the cylinder in combination with the density profile. It is found numerically that the pressure stabilizes both types of instabilities.}, year = {1997}, journal = {Journal of Plasma Physics}, volume = {58}, pages = {101-121}, month = {Jul}, isbn = {0022-3778}, doi = {10.1017/s0022377897005862}, language = {eng}, }
