 | | A team coordinated by Thierry Appourchaux has recently provided the frequency tables of the eigenmodes of oscillations for 61 stars of 3 different families. These oscillations produce very tiny but periodic variations of the luminosity of a star. More than 2200 modes were identified, which observational properties will be confronted to the theoretical knowledge of stars, probably giving way to nice refinements for stellar physics. |
 | | ESA announced the selection of the JUICE mission (JUpiter ICy moons Explorer), whose main scientific objective is the exploration of Jupiter's icy moons. IAS is planning important contributions to the remote-sensing instruments (imaging spectrometer and cameras), and a scientific contribution is also considered for Jovian seismology. |
 | | A team with a strong IAS contribution has used a novel technique to determine the star formation efficiency in dark matter halos as a function of their mass and of time. This result is an essential contribution to a pressing question in contemporary cosmology: what is the relation between dark matter halos and the loci of star formation at high redshift? |
 | | The Summer Undergraduate Student Programme “Rencontres de physique de l’infiniment grand à l’infiniment petit – 2012 – promotion E. Majorana” will be held from the 16 to the 27 July in Orsay, Palaiseau, Paris and Saclay. This Programme, designed for students who just obtained their BSc in Physics, aims at introducing the modern aspects of Fundamental and Applied Physics that cover numerous domains reaching from the smallest to the largest scales conceivable. |
