Sub-saturn planetary candidates of HD 16141 and HD 46375

Precision Doppler measurements from the Reck High-Resolution. Echelle Spectrograph reveal periodic Keplerian velocity variations in the stars HD 16141 and HD 46375. HD 16141 (G5 IV) has a period of 75.8 days and a velocity amplitude of 11 m s(-1), yielding a companion having M sin i = 0.22 M-JUP and a semimajor axis of a = 0.35 AU. HD 46375 (K1 IV-V) has a Period of 3.024 days and a velocity amplitude of 35 m s(-1), yielding a companion with M sin i = 0.25 M-JUP, a semimajor axis of a = 0.041 AU, and an eccentricity of 0.04 (consistent with zero). These companions contribute to the rising planet mass function toward lower masses.
