Accurate masses of very low mass stars: IV Improved mass-luminosity relations
X. Delfosse, T. Forveille, D. Ségransan +4
We present improved visual and near-infrared empirical mass-luminosity relations for very low mass stars (M0.6~\Msol). These relations make use of all stellar masses in this ran…

Chemical analysis of 8 recently discovered extra-solar planet host stars
N. C. Santos, G. Israelian, M. Mayor
We present the chemical analysis of a new set of stars known to harbor low mass companions, namely HD 1237, HD 52265, HD 82943, HD 83443, HD 169830, and HD 202206. In addition, we…
