The Gaia-ESO Spectroscopic Survey: First results

dr. Rodolfo Smiljanic, CAMK Toruń

The Gaia-ESO Public Spectroscopic Survey is a four years project that is obtaining high-quality spectroscopy of some 100 000 Milky Way

MOCCA - code for simulation of large star cluster evolution

prof. dr hab. Mirosław Giersz

First, I will very shortly discuss the main ideas behind the Monte Carlo method. I will point out its advantages and disadvantages. Then I will describe the newest version of the Monte Carlo code called MOCCA, which stands for MOnte Carlo star Cluster simulAtor. I will show the results of comparison between N-body and MOCCA simulations for system as large as N=200000 and briefly describe evolution of the blue straggler population in an evolving star cluster. And finally, I will discuss very preliminary results of simulations of initially very concentrated star clusters.

Nieliniowe symulacje wyjaśniające pola magnetyczne gwiazd Ap jako pozostałości po niestabilności Taylera

dr Jacek Szklarski, (Instytut Podstawowych Problemów Techniki PAN, Warszawa)

Kilka procent z gwiazd typu A posiada pewne szczególne cechy: silne powierzchniowe pola magnetyczne, długi okres rotacji i wyraźną korelację między nachyleniem osi magnetycznej i czasem obrotu.

SPICA - The Next Generation Infrared Space Mission

prof. dr hab. Ryszard Szczerba

SPICA - SPace Infrared telescope for Cosmology and Astrophysics is a common project of JAXA and ESA with a 3 m class telescope, which will be cooled for the first time to about 6K. In this way SPICA will provide a unique environment where 3 planned instruments are limited only by the cosmic background itself.
The wavelength range covered by the SPICA instruments will be from 5 up to 210 micrometers. The main scientific objectives of the mission are:
- formation and evolution of galaxies;
- formation and evolution of planetary systems; and
- life cycle of dust.
