We report the detection of five Jovian-mass planets orbiting high-metallicity stars. Four of these stars were first observed as part of the N2K program, and exhibited low rms velocity scatter after three consecutive observations. However, follow-up observations over the last 3 years now reveal the presence of longer period planets with orbital periods ranging from 21 days to a few years. HD 11506 is a G0 V star with a planet of M sin i = 4.74 MJup in a 3.85 yr orbit. HD 17156 is a G0 V star… 
FIVE NEW EXOPLANETS ORBITING THREE METAL-RICH, MASSIVE STARS: TWO-PLANET SYSTEMS INCLUDING LONG-PERIOD PLANETS AND AN ECCENTRIC PLANET
We report detections of new exoplanets from a radial-velocity (RV) survey of metal-rich FGK stars by using three telescopes. By optimizing our RV analysis method to long time-baseline observations,
Two Jovian-Mass Planets in Earthlike Orbits
We report the discovery of two new planets: a 1.94 MJup planet in a 1.8 yr orbit of HD 5319, and a 2.51 MJup planet in a 1.1 yr orbit of HD 75898. The measured eccentricities are 0.12 for HD 5319b
HD 17156b: A Transiting Planet with a 21.2 Day Period and an Eccentric Orbit
We report the detection of transits by the 3.1MJup companion to the V=8.17 G0V star HD 17156. The transit was observed by three independant observers on Sept. 9/10, 2007 (two in central Italy and one
A HIGH-ECCENTRICITY COMPONENT IN THE DOUBLE-PLANET SYSTEM AROUND HD 163607 AND A PLANET AROUND HD 164509
We report the detection of three new exoplanets from Keck Observatory. HD 163607 is a metal-rich G5IV star with two planets. The inner planet has an observed orbital period of 75.29 ± 0.02 days, a
Parameters and Predictions for the Long-Period Transiting Planet HD 17156b
We report high-cadence time series photometry of the recently discovered transiting exoplanet system HD 17156, spanning the time of transit on UT 2007 October 1, from three separate observatories. We
DETECTING TRANSITS OF PLANETARY COMPANIONS TO GIANT STARS
Of the approximately 350 extrasolar planets currently known, of order 10% orbit evolved stars with radii R* ≳ 2.5 R☉. These planets are of particular interest because they tend to orbit more massive
The HARPS search for southern extra-solar planets
We present a comprehensive analysis of 10 yr of HARPS radial velocities (RVs) of the K2V dwarf star HD 13808, which has previously been reported to host two unconfirmed planet candidates. We use
THE UPPER ATMOSPHERE OF HD17156b
HD17156b is a newly found transiting extrasolar giant planet that orbits its G-type host star in a highly eccentric orbit (e ∼ 0.67) with an orbital semimajor axis of 0.16 AU. Its period, 21.2 Earth
On the rotational behaviour of parent stars of extrasolar planets
We analysed the behaviour of the rotational velocity in the parent stars of extrasolar planets. Projected rotational velocity v sin i and angular momentum were combined with stellar and planetary
A SUBSTELLAR COMPANION IN A 1.3 yr NEARLY CIRCULAR ORBIT OF HD 16760,
We report the detection of a substellar companion orbiting the G5 dwarf HD 16760 from the N2K sample. Precise Doppler measurements of the star from Subaru and Keck revealed a Keplerian velocity
