... 2009: . ... New Wolf-Rayet Type Star. ... It was discovered that the peculiar velocity of the star is about 50km/s, and that it was discarded from a young star cluster. ... Based on the observational data from the 6-m telescope and from other sources, it was shown with high reliability that chemically peculiar stars with strong depressions in their continuum energy distributions possess the magnetic fields and rotation periods 2 and 3 times larger, respectively, than the stars with weak depressions....

Next: Stellar models Up: Introduction Previous: Photometry Contents . In a hierarchical stellar system, the separation between two neighboring stars is always much smaller than the separation of this pair from the next companion in the system, be it another pair or a single star. ... They are also numerically easier to handle than non-hierarchical systems, since each pair can be described with the standard orbital parameters, and each star with a small number of physical parameters. ... System . ...

... Initial mass function and binary stars . ... The principal goal of this study is to show that the real shape of the initial mass function for low- and intermediate-mass stars differs from the observed one. In particular, comparison of radii of eclipsing binary components and single stars shows a noticeable difference for B0V-G0V components of eclipsing binaries and single stars of the corresponding spectral type. ...

... Iron abundance in the atmospheres of components of the binary system 41 Draconis . ... 5B Iron abundances, FeI and FeII lines equivalent widths, and microturbulence velocities were found for the components of a highly eccentric spectroscopic and interferometric binary system 41 Dra from high resolution spectra obtained close to the periastron. Weighted mean values of iron abundances in the atmospheres are lgN(Fe) = 7.66 ± 0.03 and lgN(Fe) = 7.72 ± 0.03 for the component a and b, correspondingly. ...

... These measurements have invariably been interpreted as evidence for significant wide-spread small-scale structure in the HI distribution with volume densities orders of magnitude higher ($n_{HI}\sim 10^4-10^5$ cm$^{-3}$) than those implied by the parsec-scale component. Naturally, there are serious difficulties about such structures being in equilibrium with the other components of the medium, and hence about how to generate and maintain such apparently commonly encountered structures. ...

Separation of a sum of chaotic signals corrupted by Gaussian channel noise into the components with a method based on chaotic synchronous response is discussed. In order to establish the response, a procedure of iterating the maps, inverse to the maps that generate the chaotic signals, is proposed. ...

We present the general characteristics of a database for binary and multiple stars from all observational categories, specifically designed to address the awkward topics of the identification of stellar components. ...

The preliminary version of documentation of the format for the interchange of calibrated optical/IR data being developed by Tom Pauls of NRL and John Young of COAST was presented and a number of issues discussed. The proposed format is in the general form of a relational database with different components stored in FITS binary tables. ... Should there be a single data table type that includes all data types, or multiple table types, one per data type? What data types are needed? ...
