Architecture of planetary systems with and without outer giant planets I. Inner planet detections around HD 23079, HD 196067, and HD 86226
J. -B. Delisle, J. P. Faria, D. Ségransan +22
Understanding the link between outer giant planets (OGPs) and inner light planets (ILPs) is key to understanding planetary system formation and architecture. The correlation betwee…
CORALIE radial-velocity search for companions around evolved stars (CASCADES) IV: New planetary systems around HD 87816, HD 94890, and HD 102888 and an update on HD 121056
E. Fontanet, S. Udry, D. Ségransan +25
With around 200 detections of exoplanets around giant stars to date, our knowledge of the population of exoplanets orbiting evolved hosts more massive than the Sun remains limited.…
Radial velocity homogeneous analysis of M dwarfs observed with HARPS. II. Detection limits and planetary occurrence statistics
L. Mignon, X. Delfosse, N. Meunier +13
We re-determine planetary occurrences around M dwarfs using 20 years of observations from HARPS on 197 targets. The first aim of this study is to propose more precise occurrence ra…
Radial velocity homogeneous analysis of M dwarfs observed with HARPS I. Exoplanet detection and candidates
L. Mignon X. Delfosse, X. Bonfils, N. Meunier +11
The census of planets around M dwarfs in the solar neighbourhood meets two challenges: detecting the best targets for the future characterisation of planets with ELTs, and studying…
The HARPS search for southern extra-solar planets. XXXIX. HD175607 b, the most metal-poor G dwarf with an orbiting sub-Neptune
A. Mortier, J. P. Faria, N. C. Santos +16
Context. The presence of a small-mass planet (M0.1\,M) seems, to date, not to depend on metallicity, however, theoretical simulations have shown that stars with subsol…
Li depletion in solar analogues with exoplanets: Extending the sample
E. Delgado Mena, G. Israelian, J. I. González Hernández +8
We want to study the effects of the formation of planets and planetary systems on the atmospheric Li abundance of planet host stars. In this work we present new determinations of l…
New and updated stellar parameters for 71 evolved planet hosts. On the metallicity - giant planet connection
A. Mortier, N. C. Santos, S. G. Sousa +5
It is still being debated whether the well-known metallicity - giant planet correlation for dwarf stars is also valid for giant stars. For this reason, having precise metallicities…
SWEET-Cat: A catalogue of parameters for Stars With ExoplanETs I. New atmospheric parameters and masses for 48 stars with planets
N. C. Santos, S. G. Sousa, A. Mortier +8
Due to the importance that the star-planet relation has to our understanding of the planet formation process, the precise determination of stellar parameters for the ever increasin…
On the functional form of the metallicity-giant planet correlation
A. Mortier, N. C. Santos, S. Sousa +3
It is generally accepted that the presence of a giant planet is strongly dependent on the stellar metallicity. A stellar mass dependence has also been investigated, but this depend…
Chemical abundances of 1111 FGK stars from the HARPS GTO planet search program.Galactic stellar populations and planets
V. Zh. Adibekyan, S. G. Sousa, N. C. Santos +5
We performed a uniform and detailed abundance analysis of 12 refractory elements (Na, Mg, Al, Si, Ca, Ti, Cr, Ni, Co, Sc, Mn and V) for a sample of 1111 FGK dwarf stars from the HA…
Spectroscopic stellar parameters for 582 FGK stars in the HARPS volume-limited sample. Revising the metallicity-planet correlation
Sérgio G. Sousa, Nuno C. Santos, Garik Israelian +2
To understand the formation and evolution of solar-type stars and planets in the solar neighborhood, we need to obtain their stellar parameters with high precision. We present a ca…
Chemical Clues on the Formation of Planetary Systems: C/O vs Mg/Si for HARPS GTO Sample
Elisa Delgado Mena, Garik Israelian, Jonay I. González-Hernández +4
Theoretical studies suggest that C/O and Mg/Si are the most important elemental ratios in determining the mineralogy of terrestrial planets. The C/O ratio controls the distribution…
A homogeneous spectroscopic analysis of host stars of transiting planets
M. Ammler-von Eiff, N. C. Santos, S. G. Sousa +5
The analysis of transiting extra-solar planets provides an enormous amount of information about the formation and evolution of planetary systems. A precise knowledge of the host st…
