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.
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.
