ABSTRACT
Perturbation
equations for slowly rotating relativistic stars were studied until now,
in Regge Wheeler Gauge which is good for the axial part of the
perturbations. For the polar part of the perturbations though the
equations are quite complicated and not straightforward to write them in
first order system, suitable for time evolutions. With the new Gauge the
polar perturbation equations are much simpler and the trasformation to
first order system is very easy.
