Query: Landau parameters of nuclear matter in the spin and spin-isospin
  channels   The equation of state of spin and isospin polarized nuclear matter is
determined in the framework of the Brueckner theory including three-body
forces. The Landau parameters in the spin and spin-isospin sectors are derived
as a function of the baryonic density. The results are compared with the
Gamow-Teller collective modes. The relevance of $G_0$ and $G_0'$ for neutron
stars is shortly discussed, including the magnetic susceptibility and the
neutron star cooling.
