We analyse V-band photometry of the aperiodic variability in T CrB. By applying a simple idea of angular momentum transport in the accretion disc, we have developed a method to simulate the statistical distribution of flare durations with the assumption that the aperiodic variability is produced by turbulent elements in the disc. Both cumulative

We have developed a procedure based on chi2^ template fitting in order to automatically identify WDMS binary candidates from the SDSS DR6 spectroscopic data base. (5 data files).

We present infrared JHK photometry of the cataclysmic variable (CV) SDSS J123813.73 - 033933.0 and analyze it along with optical spectroscopy, demonstrating that the binary system is most probably comprised of a massive white dwarf with T eff = 12000 ± 1000 K and a brown dwarf of spectral type L4. The inferred system parameters suggest that this

The role of the entrance channel has been studied to ascertain a cause of the observed difference between the evaporation residue cross sections normalized to the fusion cross sections in the 19F + 181Ta and 16O + 184W reactions at high excitation energies. The theoretical analysis performed in the framework of the dinuclear system and advanced

We present our results on the stellar population properties of the outskirts of disk galaxies. In particular, we focus on spiral galaxies with stellar disk truncations in their radial surface brightness profiles. Using SDSS data we show color gradients. We find that the color radial profile exhibits a "U'-shape", showing a minimum at the position
