The ESA-Gaia mission is producing an unprecedented revolution in Universe sciences. The discovery of quick magnetic transitions in young ultra-fast rotating stars is quite unexpected. In this colloquium, the consequences for the inference of stellar age, for the formation of planetary systems, and for the star-planet interactions will be discussed, together with the methodology that has led to such a discovery.
Understanding the interior composition of neutron stars (NS) is an important goal of astrophysics and fundamental physics.
We are experiencing an impressive improvement of microscopy techniques with achievable resolution having approached a level that makes possible to probe individual atoms. This progress has been driven by the effort to achieve a better understanding of the physical properties of materials and devices whose feature sizes are in the range of the nanometer scale. The talk will address the importance of these techniques in characterizing novel materials of interest for the future trend in microelectronics.

Cosa si può fare utilizzando la luce, seppur debole, emessa dai bio-sistemi?
In questo colloquio, dopo una breve introduzione alla spintronica, mi soffermerò inizialmente sulla fenomenologia dell’effetto Hall di spin e dell’effetto galvanico di spin, fornendo una panoramica della situazione sperimentale.

Le misure del “rate” delle sezioni d’urto delle reazioni nucleari, che avvengono nei plasmi stellari, sono di primaria importanza per la conoscenza della Big Bang nucleosintesi e di quella stellare.
