We report precise Doppler measurements of the stars HD 216437 , HD 196050 and HD 160691 obtained with the Anglo-Australian Telescope using the UCLES spectrometer together with an iodine cell as part of the Anglo-Australian Planet Search .
Our measurements reveal periodic Keplerian velocity variations that we interpret as evidence for planets in orbit around these solar type stars .
HD 216437 has a period of 1294 \pm 250 d , a semi-amplitude of 38 \pm 4 m s ^ { -1 } and of an eccentricity of 0.33 \pm 0.09 .
The minimum ( M sin i ) mass of the companion is 2.1 \pm 0.3 M _ { JUP } and the semi-major axis is 2.4 \pm 0.5 au .
HD 196050 has a period of 1288 \pm 230 d , a semi-amplitude of 54 \pm 8 m s ^ { -1 } and an eccentricity of 0.28 \pm 0.15 .
The minimum mass of the companion is 3.0 \pm 0.5 M _ { JUP } and the semi-major axis is 2.3 \pm 0.5 au .
We also report further observations of the metal rich planet bearing star HD 160691 .
Our new solution confirms the previously reported planet and shows a trend indicating a second , longer-period companion .
These discoveries add to the growing numbers of midly-eccentric , long-period extra-solar planets around Sun-like stars .
As seems to be typical of stars with planets , both stars are metal-rich .
