| contents | The geometry of the Newman-Unti-Tamburino (NUT) vacuum solution is characterized as the unique Petrov Type D vacuum metric such that the two double principal null directions form an integrable distribution. We study expanding and twisting non-vacuum Type D metrics in this geometry, with the additional assumption $Φ_{01}=Φ_{12}=0$. We prove that these conditions determine the solutions up to a freedom in $Φ_{11}\pm 3Λ$. |
