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…
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…
The HARPS search for southern extra-solar planets XXXV. The interesting case of HD41248: stellar activity, no planets?
N. C. Santos, A. Mortier, J. P. Faria +21
The search for planets orbiting metal-poor stars is of uttermost importance for our understanding of the planet formation models. However, no dedicated searches have been conducted…
A Combined Astrometric and Spectroscopic Study of Metal-Poor Binaries
Lisa Benamati, Alessandro Sozzetti, Nuno C. Santos +1
In this work we present a study of binary systems in a metal-poor sample of solar type stars. The stars analyzed were rejected from two planet search samples because they were foun…
