Publisher: arXiv 2011
Number of pages: 43
We briefly review sources of cosmic rays, their composition and spectra as well as their propagation in the galactic and extragalactic magnetic fields, both regular and fluctuating. A special attention is paid to the recent results of the X-ray and gamma-ray observations that shed light on the origin of the galactic cosmic rays and the challenging results of Pierre Auger Observatory on the ultra high energy cosmic rays.

Flattened disks of cool dust and gas are found around almost all low mass stars shortly after their birth. This review addresses observations of the outer parts of protoplanetary disks with a focus on recent infrared and (sub-)millimeter results.

Astrochemistry aims at studying chemical processes in astronomical environments. This discipline is rapidly evolving and explores the issue of the formation of molecules of increasing complexity in particular physical conditions...

The formalism of the simple model of galactic chemical evolution (GCE) and its main ingredients are presented. It is stressed that GCE is not an astrophysical theory, but it provides a framework in which the large body of data may be interpreted.
