Nitrogen abundances in planet-harbouring stars.

ECUVILLON A., ISRAELIAN G., SANTOS N.C., MAYOR M., GARCIA LOPEZ R.J. and RANDICH S.

Abstract (from CDS):

We present a detailed spectroscopic analysis of nitrogen abundances in 91 solar-type stars, 66 with and 25 without known planetary mass companions. All comparison sample stars and 28 planet hosts were analysed by spectral synthesis of the near-UV NH band at 3360Å observed at high resolution with the VLT/UVES, while the near-IR Ni 7468Å was measured in 31 objects. These two abundance indicators are in good agreement. We found that nitrogen abundance scales with that of iron in the metallicity range -0.6<[Fe/H]<+0.4 with the slope 1.08±0.05. Our results show that the bulk of nitrogen production at high metallicities was coupled with iron. We found that the nitrogen abundance distribution in stars with exoplanets is the high [Fe/H] extension of the curve traced by the comparison sample of stars with no known planets. A comparison of our nitrogen abundances with those available in the literature shows a good agreement.
