Lithium in stars with exoplanets
Garik Israelian, Nuno Santos, Michel Mayor +1
We present a comparison of the lithium abundances of stars with and without planetary-mass companions. New lithium abundances are reported in 79 planet hosts and 38 stars from a co…
Abundances in stars with exoplanets
Garik Israelian
Extensive spectroscopic studies of stars with and without planets have concluded that stars hosting planets are significantly more metal-rich than those without planets. More subtl…
Chemical abundances of planet-host stars: Results for alpha and Fe-group elements
A. Bodaghee, N. C. Santos, G. Israelian +1
In this paper, we present a study of the abundances of Si, Ca, Sc, Ti, V, Cr, Mn, Co, and Ni in a large set of stars known to harbor giant planets, as well as in a comparison sampl…
New measurement of the Lithium-6/Lithium-7 isotopic ratio in the extra-solar planet host star HD82943 and line blending in the Li 6708 A region
Garik Israelian, Nuno Santos, Michel Mayor +1
The presence of possible blends in the spectral region of the Li resonance line at 6708 A in solar-type metal-rich stars is investigated using high resolution and high signal-to-no…
High-Resolution Spectroscopy of the Yellow Hypergiant Rho Cassiopeiae from 1993 Through the Outburst of 2000-2001
A. Lobel, A. K. Dupree, R. P. Stefanik +7
We present an overview of the spectral variability of the peculiar F-type hypergiant Rho Cas, obtained from our long-term monitoring campaigns over the past 8.5 years with four spe…
