Stellar metallicity strongly correlates with the presence of planets and their properties. To check for new correlations between stars and the existence of an orbiting planet, we determine precise stellar parameters for a sample of metal-poor solar-type stars. This sample was observed with the HARPS spectrograph and is part of a program to search

The VSA (Very Small Array) has made CMB observations in three different configurations, corresponding to different multipole order (l) ranges: compact for l=150-800 (Taylor et al. 2003, Cat. J/MNRAS/341/1066), extended for l=300-1500 (Dickinson et al. 2004MNRAS.353..732D) and super-extended for l=600-2500. The corresponding areas have been surveyed

The sulphur-containing proteinaceous amino acids l-cysteine, l-cystine and l-methionine were irradiated in the solid state to a dose of 3.2 MGy. This dose corresponds to that delivered by radionuclide decay in a timescale of 1.05 x 10(9) years to the organic matter buried at a depth > 20 m in comets and asteroids. The purity of the sulphur

A photometric method to detect planets orbiting around shortperiodic binary stars is presented. It is based on the detection of eclipse-signatures in the reflected light of circumbinary planets. Amplitudes of such 'reflected eclipses' will depend on the orbital configurations of binary and planet relative to the observer. Reflected eclipses will
