We present 12 years of precision Doppler data for the very nearby G3 star HD?102365, which reveals the presence of a Neptune-like planet with a 16.0 M Earth minimum mass in a 122.1 day orbit. Very few Super Earth planets have been discovered to date in orbits this large and those that have been found reside in multiple systems of between three and six planets. HD?102365?b, in contrast, appears to orbit its star in splendid isolation. Analysis of the residuals to our Keplerian fit for HD?102365… Expand

The Anglo-Australian planet search. XXI. A gas-giant planet in a one year orbit and the habitability of gas-giant satellites
We have detected the Doppler signature of a gas-giant exoplanet orbiting the star HD 38283, in an eccentric orbit with a period of almost exactly one year (P = 363.2 ± 1.6 d, m sin i = 0.34 ± 0.02 MExpand
A DOUBLE PLANETARY SYSTEM AROUND THE EVOLVED INTERMEDIATE-MASS STAR HD 4732
We report the detection of a double planetary system orbiting around the evolved intermediate-mass star HD 4732 from precise Doppler measurements at Okayama Astrophysical Observatory and AustralianExpand
MINERVA: Small Planets from Small Telescopes
The Kepler mission has shown that small planets are extremely common. It is likely that nearly every star in the sky hosts at least one rocky planet. We just need to look hard enough - but thisExpand

Correlations between the stellar, planetary, and debris components of exoplanet systems observed by Herschel
Context. Stars form surrounded by gas- and dust-rich protoplanetary discs. Generally, these discs dissipate over a few (3–10) Myr, leaving a faint tenuous debris disc composed of second-generationExpand
Forever Alone? Testing Single Eccentric Planetary Systems for Multiple Companions
Determining the orbital eccentricity of an extrasolar planet is critically important for understanding the system's dynamical environment and history. However, eccentricity is often poorly determinedExpand
The Super Earth-Cold Jupiter Relations
We report relations between inner ($ 1$ au) giant planets (mass $>0.3~M_{\rm J}$, or cold Jupiters) around Sun-like stars, based on data from both ground-based radial velocity (RV) observations andExpand
Truly eccentric – II. When can two circular planets mimic a single eccentric orbit?
When, in the course of searching for exoplanets, sparse sampling and noisy data make it necessary to disentangle possible solutions to the observations, one must consider the possibility that whatExpand
Jupiter analogues and planets of active stars
Combined results are now available from a 15 year long search for Jupiter analogues around solar-type stars using the ESO CAT + CES, ESO 3.6 m + CES, and ESO 3.6 m + HARPS instruments. They compriseExpand
An upper boundary in the mass-metallicity plane of exo-Neptunes
With the progress of detection techniques, the number of low-mass and small-size exoplanets is increasing rapidly. However their characteristics and formation mechanisms are not yet fully understood.Expand

An extrasolar planetary system with three Neptune-mass planets
TLDR
Simulations show that the system of three Neptune-mass planets orbiting the nearby star HD 69830 is in a dynamically stable configuration and theoretical calculations favour a mainly rocky composition for both inner planets, while the outer planet probably has a significant gaseous envelope surrounding its rocky/icy core.
