  In the current paper we present some new data on the issue of quasi-normal
modes (QNMs) of uniform, neutron and quark stars. These questions have already
been addressed in the literature before, but we have found some interesting
features that have not been discussed so far. We have increased the range of
frequency values for the scalar and axial perturbations of such stars and made
a comparison between such QNMs and those of the very well-known Schwarzschild
black holes. Also addressed in this work was the interesting feature of
competing modes, which appear not only for uniform stars, but for quark stars
as well.
