Orbital and physical properties of planets and their hosts: new insights on planet formation and evolution
V. Zh. Adibekyan, P. Figueira, N. C. Santos +7
We explore the relations between physical and orbital properties of planets and properties of their host stars to identify the main observable signatures of the formation and evolu…
New and updated stellar parameters for 90 transit hosts. The effect of the surface gravity
A. Mortier, N. C. Santos, S. G. Sousa +5
Context. Precise stellar parameters are crucial in exoplanet research for correctly determining of the planetary parameters. For stars hosting a transiting planet, determining of t…
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…
Is there plenty of metal-poor stars with planets in the Galactic thick disk?
V. Zh. Adibekyan, N. C. Santos, S. G. Sousa +2
We performed an uniform spectroscopic analysis of 1111 FGK dwarfs observed as part of the HARPS GTO planet search program. We applied a purely chemical approach, based on [alpha/Fe…
Kinematics and chemical properties of the Galactic stellar populations. The HARPS FGK dwarfs sample
V. Zh. Adibekyan, P. Figueira, N. C. Santos +7
(Abridged) We analyze chemical and kinematical properties of about 850 FGK solar neighborhood long-lived dwarfs observed with the HARPS high-resolution spectrograph. The stars in t…
Searching for the signatures of terrestrial planets in F-, G-type main-sequence stars
J. I. González Hernández, E. Delgado-Mena, S. G. Sousa +4
We have studied the volatile-to-refractory abundance ratios to investigate their possible relation with the low-mass planetary formation. We present a fully differential chemical a…
