Using a object-based analysis and verification approach a comparison of TRMM satellite precipitation dataset to the WRF model simulation was performed. The comparison of three years of data showed a general agreement but also some differences between the datasets. Notably, there is more precipitation in the model, the trajectories in the ITCZ are straighter in the WRF simulation and in the central part of ICTZ the movement in the TRMM dataset is both eastward and westward, while in the WRF simulation the westward movement is dominant.

COBISS.SI-ID: 2305380We present an Echelle+CCD, high signal-to-noise ratio, high-resolution (R = 20,000) spectroscopic atlas of 108 well-known objects representative of the most common types of peculiar and variable stars. The wavelength interval extends from 4600 to 9400 A and includes the RAVE, Gaia, and HERMES wavelength ranges. Multi-epoch spectra are provided for the majority of the observed stars. The atlas aims to provide a homogeneous database of the spectral appearance of stellar peculiarities, a tool useful both for classification purposes and inter-comparison studies.

COBISS.SI-ID: 365697Theories of thick-disk formation can be differentiated by measurements of stellar elemental abundances. We have undertaken a study of metal-poor stars selected from the RAVE spectroscopic survey. We find that the [?/Fe] ratios are enhanced, implying that enrichment proceeded by purely core-collapse supernovae. So a direct accretion of stars from dwarf galaxies similar to surviving dwarf galaxies today did not play a major role in the formation of the thick disk.

COBISS.SI-ID: 366209The 13th , International Workshop entitled "What Comes Beyond the Standard Models" (www.fiz.uni-lj.si/bled2010bsm/) was organized jointly with colleagues from Copenhagen and Paris. It attracted a small group of theoreticians actively working on finding answers to the open questions of the elementary particle physics and cosmology. Discussions were very open, critical and detailed, and also taking place interactively over the internet with researchers around the world (COBISS.SI-ID 2291556 , 2291812, 2292068, 2292324).

COBISS.SI-ID: 2285668The discovery that the Galactic center emits flares at various wavelengths represents a puzzle concerning their origin, but at the same time it is a relevant opportunity to investigate the environment of the nearest super-massive black hole. In this paper we shall review some of our recent results concerning the tidal evolution of the orbits of low mass satellites around black holes, and the tidal effect during their in-fall. We show that tidal interaction can offer an explanation for transient phenomena like near infra-red and X-ray flares from Sgr A*.
