Abundances in stars with exoplanets
نویسنده
چکیده
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 subtle trends of different chemical elements begin to appear as the number of detected extrasolar planetary systems continues to grow. I review our current knowledge concerning the observed abundance trends of various chemical elements in stars with exoplanets and their possible implications.

Lithium in stars with exoplanets⋆
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 comparison sample. When the Li abundances of planet host stars are compared with the 157 stars in the sample of field stars of Chen et al. (2001) we find that the Li abundance distribution is significantly different, an...
متن کاملMetallic fingers and metallicity excess in exoplanets host stars : the accretion hypothesis revisited
While the metallicity excess observed in the central stars of planetary systems is confirmed by all recent observations, the reason for this excess is still a subject of debate : is it primordial, is it the result of accretion or both? The basic argument against an accretion origin is related to the mass of the outer convective zones which varies by more than one order of magnitude among the co...
متن کاملModels of very-low-mass stars, brown dwarfs and exoplanets
Within the next few years, GAIA and several instruments aiming to image extrasolar planets will be ready. In parallel, low-mass planets are being sought around red dwarfs, which offer more favourable conditions, for both radial velocity detection and transit studies, than solar-type stars. In this paper, the authors of a model atmosphere code that has allowed the detection of water vapour in th...
متن کاملImproved Parameters for Extrasolar Transiting Planets
We present refined values for the physical parameters of transiting exoplanets, based on a selfconsistent and uniform analysis of transit light curves and the observable properties of the host stars. Previously it has been difficult to interpret the ensemble properties of transiting exoplanets, because of the widely different methodologies that have been applied in individual cases. Furthermore...
متن کاملElemental abundances in the Blanco 1 open cluster
High resolution spectroscopy is used to determine the detailed chemical abundances of a group of eight Fand G-type stars in the young open cluster Blanco 1. An average [Fe/H] of +0.04 ±0.02 (internal error) ±0.04 (external error) is found, considerably lower than a previous spectroscopic estimate for this cluster. The difference is due mainly to our adoption of significantly cooler temperatures...
