Planetary companions around two solar-type stars: HD 195019 and HD 217107

We have enlarged the sample of stars in the planet search at Lick Observato ry. Doppler measurements of 82 new stars observed at Lick Observatory, with additional velocities from Keek Observatory, have revealed two new planet candidates. The G3 V/IV star, HD 195019, exhibits Keplerian velocity variat ions with period of 18.27 days, an orbital eccentricity of 0.03 +/- 0.03, a nd M sin i = 3.51 M-JUP. Based on a measurement of Ca II H and K emission, this star is chromospherically inactive. We estimate the metallicity of HD 195019 to be approximately solar from ubvy photometry. The second planet ca ndidate was detected around HD 217107, a G7 V star. This star exhibits a 7. 12 day Keplerian period with eccentricity 0.14 +/- 0.05 and M sin i = 1.27 M-JUP. HD 217107 is also chromospherically inactive. The photometric metall icity is found to be [Fe/H] = +0.29 +/- 0.1 dex. Given the relatively short orbital period, the absence of tidal spin-up in PID 217107 provides a theo retical constraint on the upper limit of the companion mass of less than 11 M-JUP .
