Context. The recent discovery of three giant planets orbiting the extremely metal-poor stars HIP 11952 and HIP 13044 have challenged theoretical predictions of the core-accretion model. According to this, the metal content of the protoplanetary disk from which giant planets are formed is a key ingredient for the early formation of planetesimals prior to the runaway accretion of the surrounding gas. Aims. We reanalyzed the original FEROS data that were used to detect the planets to prove or…

The properties of planets around giant stars
Context: More than 50 exoplanets have been found around giant stars, revealing different properties when compared to planets orbiting solar-type stars. In particular, they are Super-Jupiters and are
A planetary system and a highly eccentric brown dwarf around the giant stars HIP67851 and HIP97233
Context: So far more than 60 substellar companions have been discovered around giant stars. These systems present physical and orbital properties that contrast to those detected orbiting less evolved
An eccentric companion at the edge of the brown dwarf desert orbiting the 2.4 M⊙ giant star HIP 67537
We report the discovery of a substellar companion around the giant star HIP 67537. Based on precision radial velocity measurements from CHIRON and FEROS high-resolution spectroscopic data, we derived
The chemical composition of stars hosting small exoplanets (with radii less than four Earth radii) appears to be more diverse than that of gas-giant hosts, which tend to be metal-rich. This implies
Giant planets around two intermediate-mass evolved stars and confirmation of the planetary nature of HIP 67851c
Context. Precision radial velocities are required to discover and ch aracterize planets orbiting nearby stars. Optical and near infrared spectra that exhibit many hundreds of absorption lines can
The GAPS Programme with HARPS-N at TNG
Context. Statistical studies of exoplanets have shown that giant planets are more commonly hosted by metal-rich dwarf stars than low-metallicity stars, while no such correlation is evident for lower
RAFT I: Discovery of new planetary candidates and updated orbits from archival FEROS spectra
A recent reanalysis of archival data has lead several author s to arrive at strikingly different conclusions for a number of planet-hosting candidate stars. In particular, some radial velocities
Planet Traps and First Planets: The Critical Metallicity for Gas Giant Formation
The ubiquity of planets poses an interesting question: when are first planets formed in galaxies? We investigate this by adopting a theoretical model where planet traps are combined with the standard
Two planets around Kapteyn's star: a cold and a temperate super-Earth orbiting the nearest halo red dwarf
Exoplanets of a few Earth masses can be now detected around nearby low-mass stars using Doppler spectroscopy. In this paper, we investigate the radial velocity variations of Kapteyn's star, which is
The Test Case of HD 26965: Difficulties Disentangling Weak Doppler Signals from Stellar Activity*
We report the discovery of a radial velocity signal that can be interpreted as a planetary-mass candidate orbiting the K dwarf HD26965, with an orbital period of 42.364$\pm$0.015 days, or


We propose a scenario to account for the surprising orbital properties of the planet orbiting the metal-poor red horizontal branch star HIP 13044. The orbital period of 16.2 days implies that the
Planetary companions around the metal-poor star HIP 11952
Aims. We carried out a radial-velocity survey to search for planets around metal-poor stars. In this paper we report the discovery of two planets around HIP 11952, a metal-poor star with [Fe/H]=−1.9
A Hot Uranus Orbiting the Super Metal-rich Star HD 77338 and the Metallicity-Mass Connection
We announce the discovery of a low-mass planet orbiting the super metal-rich K0V star HD 77338 as part of our ongoing Calan-Hertfordshire Extrasolar Planet Search. The best-fit planet solution has an
Study of the impact of the post-MS evolution of the host star on the orbits of close-in planets - II. A giant planet in a close-in orbit around the RGB star HIP 63242
Context. More than 40 planets have been found around giant stars, revealing a lack of systems orbiting interior to ∼0.6 AU. This observational fact contrasts with the planetary population around
The recent discovery of two Earth-mass planets in close orbits around an evolved star has raised questions as to whether substellar companions can survive encounters with their host stars. We

The detection of a close-in giant planet around a metal-poor star belonging to a group of stars that formed in a satellite galaxy of the Milky Way, which most likely has an extragalactic origin.
