ARES v2 - new features and improved performance
S. G. Sousa, N. C. Santos, V. Adibekyan +2
Aims: We present a new upgraded version of ARES. The new version includes a series of interesting new features such as automatic radial velocity correction, a fully automatic conti…
Chemical abundances and kinematics of 257 G-, K-type field giants. Setting a base for further analysis of giant-planet properties orbiting evolved stars
V. Zh. Adibekyan, L. Benamati, N. C. Santos +9
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 257 G- and K-type evolved stars…
Determination of the spectroscopic stellar parameters for 257 field giant stars
S. Alves, L. Benamati, N. C. Santos +6
The study of stellar parameters of planet-hosting stars, such as metallicity and chemical abundances, help us to understand the theory of planet formation and stellar evolution. He…
Homogeneous spectroscopic parameters for bright planet host stars from the northern hemisphere
S. G. Sousa, N. C. Santos, A. Mortier +6
Aims. In this work we derive new precise and homogeneous parameters for 37 stars with planets. For this purpose, we analyze high resolution spectra obtained by the NARVAL spectrogr…
Exoplanets: Gaia and the importance of ground based spectroscopy follow-up
L. Benamati, V. Zh. Adibekyan, N. C. Santos +1
The search for extrasolar planets has developed rapidly and, today, more than 1700 planets have been found orbiting stars. Thanks to Gaia, we will collect high-accuracy astrometric…
