| dc.description.abstract | Precise Doppler measurements from the Anglo-Australian Telescope (AAT) UCLES spectrometer reveal periodic Keplerian velocity variations in the stars HD 160691 and HD 27442. HD 160691 has a period of 743 days, a semiamplitude of 54 m s~1, and a high eccentricity, e\0.62, typical of extrasolar planets orbiting beyond 0.2 AU. The minimum (M sin i) mass of the companion is 1.97 MJ and the , semimajor axis is 1.65 AU. HD 27442 has a 415 day period, a semiamplitude of 32 m s~1, and an eccentricity of 0.058. The minimum mass is 1.43 MJ and the semimajor axis is 1.18 AU. This is the first , extrasolar planet orbiting beyond 0.2 AU that is in a circular orbit similar to solar system planets. The photon-limited precision of AAT/UCLES measurements is 3 m s~1 as demonstrated by stable stars and Keplerian fits to planet-bearing stars. In addition, we present confirmation of four previously announced planets. | en |
